can you explain for me the added value of the increased pressure injectors, I would guess that you get a better burn or combustion consumption of your fuel which would mean more on demand power, what I'm wondering really is does this mean you will see an increase in fuel economy?

@@InjectorRehab I was going to ask a similar question about the Jeep injectors as far as what flow rate to buy the 19lb flow rate or 23lb my Jeeps a 99 off road setup I’m working on upgrading spark & fuel delivery for reliability more then performance I guess you could say though performance increases are absolutely welcome 😆 I don’t have the cats my muffler is a flow master & I guess you could say it has a cai since the factory air box is gone & everything is replaced with a snorkel setup so I don’t suck in water which I guess is a version of a cold air setup since I’m definitely not sucking in hot engine air any longer I’m going to say the 23lb 4-hole injectors are probably what I would want to buy correct? Eventually I’ll add a 62mm throttle body for some additional air in to go along with the head intake & exhaust that was all cleaned up & gasket matched as well for a little extra help in the performance department
