Hi Hammad, the T9464 VTA does NOT have the option to install an optional trumpet. Our trumpets are exclusively compatible with our Mach 2/Hybrid/Respons/Deceptor Pro II valves only and NOT for our DV+’s or VTA’s. Thanks. I’m not sure why you would have been sent a trumpet as a gift with your purchase, I’d recommend asking whoever you purchased from.

Hi Brandon, could you please email us at [email protected] and let us know when this fluttering is occurring? Is it occurring at high RPM’s or low RPM’s. We’ll also need some additional information to help get a better understanding as to what is going on such as install pics and perhaps a video showcasing the fluttering that you’re hearing. Thanks.

Hi, for fitment related questions - please contact our support team at [email protected]! Thanks.

Hi Luke, thanks for contacting us. Could you please contact us at [email protected]? We'd be more than happy to help there.

I know it’s a 12v and a aux input for the MAC valve side but not sure what wires are what and no clue about the GFB side

Hi Xyez, thanks for contacting us. Could you please contact us at [email protected]? We'd be more than happy to help!

Hi Allen, yes. With the T9358 DV+ you will be able to uninstall the DV+ from your OE diverter valve and solenoid and reassemble your OE diverter valve if needed.

@@gfbvideos ok cool. My brother has a 12 cc w k04 swap and the valve started making noise. Come to find out he found the o-ring to be blown out after I sent the comment

@@allenj9038 Thanks for getting back to me. If in the case you're after a replacement O-ring, contact us at [email protected]!

@@gfbvideos well find out tomorrow my friend lol. Thank you for your help

Hi, the issue on most of the vehicles the T9352 is intended for is clearance, as the VTA is quite a bit taller than the DV+ version. A little secret, the VTA we sell for the Mercedes (T9458) will fit the same turbo and diverter valve as the T9352, but it probably won't have enough room around it to fit. If you can let me know what vehicle you've got, I can advise if you've got a chance of fitting one on there. Best to contact us through our support channel via the website, as we may need you to send some photos of your factory diverter valve.

@@gfbvideos I've got a Peugeot 508 1.6 THP. Same as the 207 and mini

@@cjerp The location of the diverter valve on the 508 is actually different to the Mini, which in your case works in your favour. We have had a customer fit a T9458 to a 508, however the top of the solenoid does press against the plastic turbo intake pipe, which is why we don't list it as an official fitment. If you'd like to see a photo of the installation please contact us through support.

Hi Robert, the DV+ that is used in this video is when we were using that older T9351 DV+ style packaging many years ago. We've since made changes to our packaging whereas the counterfeit DV+'s will still use this old-style packaging. If in the case you have any questions regarding whether your DV+ is a genuine GFB product - please do not hesitate to contact our support team at [email protected] so that we'd be able to help.

Hi, our DV+ works by replacing the plastic valve parts of your OE diverter valve with an anodized billet aluminum housing and brass piston that ensures strength and reliability no matter how much boost you run. Our pilot-actuation system allows the valve to progressively open in response to boost pressure. By retaining the factory solenoid as well, the DV+ is able to open and clos reliably without ever exceeding the solenoids capability.

Hi Florian, unfortunately our G Force 3 will NOT be compatible with a vacuum actuated internal wastegate. Our G Force 3 is designed to be compatible with traditional pneumatically actuated wastegate actuator that uses pressure. The issue with this is that the pressure in a pressure actuated wastegate is part of what makes the whole system closed loop. The pressure that’s going to the solenoid is the pressure that you’re controlling. With a vacuum actuated one, the vacuum is a fixed pressure from the vacuum pump.

Yes. Or 4 gear.

Hi, could you please contact [email protected], we'd just like to go through some troubleshooting steps so that we'd be able to get a better understanding as to what is going on.

Hi Yien, thanks for contacting us. Unfortunately, we do not have the T9388 DV+ listed as compatible with the MY19-20 C200. Thanks.

Hi, when installing the provided screws - you’ll need a 6mm hex key.

Hi, for the non twincharged variants of the 1.4TSI from MY14-ON, we currently have the T9430 VTA listed as compatible and not the T9381 DV+. If in the case you have any further questions, please do not hesitate to contact us at [email protected]

Hi, thank you for contacting us. Would you be able to send us some photos of your vehicles OE diverter valve and its location to [email protected]? We'd be more than happy to help check to see whether we may have something that would be compatible with your vehicle. Thanks.

Hi, our DV+ will be full silent alike your OE diverter valve and will recirculate all air back into the intake. If in the case you were interested in a VTA, please contact us at [email protected]. Regarding the potential for any CEL codes, when installed correctly - our valves shouldn't cause a CEL light to be triggered, however, please contact us if in the case it is and we'll be more than happy to help by going through some troubleshooting steps! Thanks.

Hi, thank you for contacting us. Could you please contact our support team at [email protected], our support team will be more than happy to help you there!

Hi Joey, thanks for contacting us. Could you please contact us at [email protected], we'd be more than happy to help.

Hi Carl, thanks for contacting us. We've now adapted the T9353 DV+ so that it is now compatible with both manual and automatic applications. I'd highly recommend having a pre-read of our instructions to help aid with this installation.

Hi, you will not need to retune your vehicle after installing one of our valves. You would simply need to tune the valve to your vehicle instead!

Hi, thank you for contacting us. Unfortunately, we were out of office over the Easter break. We'd be more than happy to help, could you please contact us at [email protected]. Thanks.

Yeah that is correct! That's the original style box that the DV+ came with back in 2014 when we made this video. Since then we've swapped to a different style of box, but the counterfeit part manufacturers haven't copied the new box (yet).

The P0243 error looks to be related to the boost control solenoid, not the diverter valve.

You will not need to tune your vehicle after installing the valve. You simply need to adjust the spring pre-load on the valve to suit your particular vehicle

Hi Ricardo, please contact our support team at [email protected]! We'll be more than happy to help provide you with more information.

its ok nothing to worry about. if u get flutter while accelerating its bad for turbo. but just a little when u release pedal does nothing bad its just air coming in opposite direction hitting the turbo blades

Flutter puts wear on your turbo, you don’t want flutter unless you want to buy a new turbo prematurely Edit: it sounds great though :)

Hi, for that video we have removed the trumpet just to make it easier to see the piston when adjusting spring pre-load. it’s worth noting that with the standard trumpet installed - it will only make a “whooshing” sound when coming off throttle. You will only get a whistling effect with the optional “whistling” trumpet. Thanks

Thanks

Hi, for this installation you would need basic tools such as a 6mm hex key, flat head screwdriver and adjustable spanner. Please contact our support team at [email protected] for more information.

Sounds exciting! Let us know by tagging us @gofastbits on our various socials. We'd love to see how you find it.

@@gfbvideos got just the DV+ add on to my original valve. Mine tested good. But just pulling out of the shop I felt the difference in tip in boost.

Hi! Please contact our support team at [email protected]! We'd be more than happy to help.

Great question! Our pilot-actuated operating system alters the operation of the DV+ so that the solenoid only has to control airflow through a small passage that is then used to open and close the piston (rather than opening and closing the piston directly). This feature also improves on the factory system by opening the valve progressively in response to boost pressure, so that it opens as much as required to get the job done - resulting in better throttle response. For more information, please contact our support team at [email protected]!

​@@gfbvideoshello does the solenoïd need an adaptation time?

@@Di-Mit Hi, thanks for reaching out. Our integrated solenoid DV+’s will not need any “adaption time”. The associated performance related benefits can be felt immediately after installing. Thanks

@@gfbvideos thanks

Hi! Please contact our support team at [email protected]!

Hi Juan, thank you for contacting us! Applying oil to the main piston is NOT critical to the operation of the valve. Oiling the piston helps aid with the bedding process between the piston and body. There should also be a sufficient amount of engine blow by to help keep this piston lubricated. Thanks

Hi, thank you for contacting us! As per our instructions, we only recommend applying a light coating of engine oil to the piston to help aid with the installation process. This shouldn’t need to be reapplied as a constant form of maintenance as there should be a sufficient amount of engine blow by to help keep the piston lubricated. The piston will still be able to run dry without problems. Oiling is recommended as it can help with the bedding in process.

@@gfbvideos many thanks 🙏

Hi Lior, yes. The DV+ can be installed on your vehicle without having to retune your vehicle.
