Ok i have a 2000 transam that just got forged pistons and rods and i got it all back together with bigger injectors cuz it needed em and it would cut out and sputter around 2k but at 3k it would wake up and run fine it had low fuel pressure at idle and when i rev it up so i put a new racetronix fuel pump in it and it fixed the psi problem but now it runs great but doesn't want to drive for crap, im hoping it just needs a tune.. Any help guys??

 

I cant even give it gas when driving or it cuts out real bad and sputters, if texas speed could give their 2 cents that would be great cuz im gunna call them on monday anyway.

 

it definitely needs a tune if you put bigger injectors in there, I would highly advise against driving it untuned, very bad for your motor and your wallet.

 

Dude when I did my H/c built motor with injectors and a pump it wouldn't even idle for a half a second. I wouldn't dare even put it up the road. Get a trailer, and take it to a tuner.

 

 

Youre calling me stupid? Care to elaborate on that.

 

actually I was agreeing with you.....

 

ok cool, so OP whats the laest and greatest with the car?

 

How much bigger are the injectors you put in? Hopefully not a lot bigger. You might end up having more problems than just a tune.
