If you dropped 60' from 2.2 to 2.0 you can expect .4 drop in your ET. Might not be exact with turbos but for NA it is very accurate.

I've discovered it's more like 125-150% drop in the ET, not 200%. I'll go back and look at all 14 runs I have in the Solstice,

I witnessed an auto GXP do 2.0 flat repeatedly on stock tires, just yesterday.

It's all about the driver in a manual car. This guy is a holeshot KING: Launch_Tips
MIR is a great track, I've pulled a 1.4 60ft there on drag radials. (NOT in the Solstice)

The GMPP tune limits torque to 50% with the brake applied also reduces power (I believe by closing the throttle) during the shifts to protect the transmissions. Long gone are the days of a GN running a 200-R4 staying in boost from line to traps.
