I have Used the guide many times !

i seen on here someone said that the p7100 didnt have a fuel screw in the back, now i got mine turned and more power and a lil bit of smoke. i know for sure they didnt mess with the plate so ther deff. is a screw on it......

But also does anyone have problems with their throttle cable breaking or have alot of slack in it???

I think what you’re referring to is what people call the Smoke screw. It’s on the back of the AFC housing

Dustin, there is recall on the throttle cable:

Check it out: Recall #970 - throttle cable

alright ill call the dealership and get that fixed
i appreciate it

alright while im at asking questions
when my trucks at 55 and i stomp it, it want gear down, i thought its supposed to but i just wanted to know if yall know why it would, but its geared 3.55 and it has stock exhaust except its straight piped and the idiot that put the delete pipe on bent it.
so any suggestions would be appreciated?

You will probably get more better exposure if you start your own thread.
