I'm planning on stilling ZZP's stage 2 on my 05 Cobalt SS. I dusted off my HP tuners yesterday to make sure that all works (um, it's been sitting in my computer desk for the better part of a decade.)

After upgrading to 3.2 and making sure everything works, I did a 10-100 mph pull. (closed course, professional driver. Do not try and home.)

Anyway, my time was 15.37 seconds from 10-100. Which is okay given that I didn't clean out my trunk, roll up the windows, or even shift too aggressively.

But one thing that really stood out is the fact that my throttle position only read 88.2%. I'm not sure if that's me not getting the peddle all the way down, the throttle position center, or HP tuners reading the position incorrectly.

Anyway have any experience with this? I'm going to try and get back out this weekend for a few more pulls instead of just this one.

thats completely normal on a gm vehicle with electronic throttle.

Sweet. Then I won't worry about it.
