Which "chip upgrade" really is the best? This site

[85_305]

Really? The car pulls harder in a higher RPM in second gear? Since we have the same motors, would that also be true for mine?
How much overall did you gain w/ the 60*v6 chip? Was it notably better?

you don't have the same motors. the 3100 has a roller cam and a different intake. i found my 97 lumina to be faster if i shifted it at6000rpm in first and second due the the fact the power really comes on about 4200rpm. almost seems like i'm giving it half throttle then at 4200rpm, i roll it to the floor. even the engine sounds different. if i let the car shift at 5500rpm, the rpm would drop to about 3800rpm, below that power jump. if i wait to 6000rpm it drops right to 4200rpm where it's making all that extra power. for me it was like anything below 4200rpm, it was low on power, or untuned.

i am talkin bout my old beretta, it had a 3.1mpfi i ran it 2 6000rpm and it gave me a better time at the track, same with my 3.1 corsica i had.

Hmmm. This is weird. My car stops pulling in the HIGH r's, I wonder why yours doesnt?

[torq455]

yeah, i drove two 3.1's, both 94, one was an RS 5 spd, the Z is an auto. i thought they'd never get to 6Krpm in second! maybe your tac was off.

What about the possability of different gear ratio in the axle???? Bill//

[torq455]

depends on what car you are talking about. beretta, cavalier, if an auto with the 125C, the FDR should be 3.18. 5 spd, you're outta luck. if you have an auto, you can't change the FDR unless you convert to a 4t60. then you can go from 3.33, 3.43, and 3.73.

it gave it higher rpms for second so it picked up second faster, it was a 92 corsica and a 93 beretta, made both of em bout a tenth or two faster
