Guys, I think i need to get a new chip or reprogram my existing chip.

I have a 99 5.7 block with vortec heads and the GM TBI to Vortec manifold, cam is Edelbrock Performer with duration at 204 intake 214 exh, Lift is .425 intake and .448 exh with 1.52 roller tip rockers.

for a slightly modifed motor, who makes the best computer chip or can reprogram mine?

Thanks

 

not to familiar with the early s10 stuff, but isnt it a obd1 reflashable pcm? find a tuner with tunercats to reflash and tune it.

I dont know anything about it.. except I came on here thinking you might be thinking of buying one of those Gyp-chips for $50.

Should'a known you weren't dumb. My apologies.
