i have been trowing a P0171. LTFT 19.5 Will bigger injectors and a tune fix this problem. im runnin a 2.8 on what i believe to be 42.5's

bump

 

Just a tune in general will fix the problem. No need for larger injectors unless you want to pulley down.

 

thanks i am gonna go to 60's just incase i wanna do stuff later on

 

perfect.

 

ShortStack...he's runnin a 2.8. He needs to be on 60's. 2.9 is the lowest you can go on the 42's safely. Get the 60's and a tune and all will be well OP

 

No he does not. A 2.9 is not the lowest you can go. I ran a 2.8 just fine for about 7 months. Idcs were not above 100.

As long as you have a tune, you can use the 2.8 on 42s. Hell i didnt even have cooling mods...

 

That's not what I've been told from many different tuners and drivers alike on this site. Ur actually the first person that's ever told me otherwise
