I went out today to play with the Gtech. I couldn't find anywhere to do a full 1/4 so all I could do is 1/8 test. My 1/8 times were 10.378 at 70.64 and 10.379 at 70.67.

Are these times about right for a reg cab sportside truck with two people? Only mods are a 2 chamber flow, k&n intake, and a hypertech programmer. btw, truck has a 4.8

What is our trucks stock redline and about how much do the reg cab sportsides weigh? Thanks

 

Do you have the old style or new style G-Tech??

 

New, GTech Pro RR

 

I just got my RR also, ran it last night with the CTS-V got sub 5 second 0-60 and a 8.3 1/8 mile.......Mine working good!

 

i am at about 9.9 sec for the 1/8 with my Gtech.

 

So I guess mine is about right then. That stall probably helps you to get that ext. cab moving.

 

yup.

before yank = 15.7
after yank = 15.3
