Told ya! Nice job.

Did you figure out the 90% thing or was that just something that you visibly saw but was incaccurate?

Outstanding!

I don't have the mods you have, but boy, the LS2 TB added some power. I'll find out more when I hit the track.

This mod feels better than all the work and extra comp ratio than the ported heads had on car .
Just read a thread where guy was getting 29 extra rwhp and 20 ft lbs of tq ?
Will find out when get car on dyno .
A bit concerned about not getting actual WOT on physical TB but ECU reporting is is 100% .
Can’t find any info on that

I just took a video of mine opening all the way I'll post it in a bit.

It should open all the way. Maybe you can post a video too? If it doesn't, it's defective. When I looked at your tune, the scaler was .182. Did you change that?

Not sure how much I gained, but it feels like I gained torque and horsepower at all rpms. Gains are low and high. Very, very pleased.
