If I just have 4:10s, LS1 driveshaft, cutout, 2OTL and plugs/wires will a PCMforless even make my car any faster?

 

They might be able to pick up alittle but I doubt to much since your mod list is kind of small. I had Bryan from pcmforless tune my car along time ago he did a good job.

 

Hi,
We can pick you up 15-20 Hp with a tune. We can fix up the speedometer for the gears and if you are a six speed we can get rid of the skip shift. If it is an auto we can firm up your shifts and improve your shift points. We also can lower your fan temps and improve your mileage slightly.

 

yep Alvin can help ya out.

if you don't have a tune they can get the quoted power out of it. it will run better than factory too.

a car untuned to a tuned car (properly) you will get 15-20hp... so yes they can make your car faster if you have a stock tune
