I would guess the bigger injectors are causing the issue.
thats all im hoping for, that way i don't have to pull the injectors back out again untill i put the heads on.
Do you have HPTuners or a programmer? Sounds like you need to scale down your injector pulse width.
The IFR (injector flow rate) VS. Map needs to be increased but I would get with Allen about it and see what he says!
yep he will be retuning the truck after the heads are on. thanks
Not sure what size injectors you put in, but if they are bigger, that's why it's rich.Quote:

The ifr table needs to be adjusted, plus it's about time to scan your truck and see how it's running, time for a retune.
later,
