he'll definitely test it out, he tows his drag car to the track and bonneville quite a bit.
As far as heat, the tvs just doesn't heat up. While it's on the dyno all this time, iat's never reach over 109degs! That's with back to back runs and 72deg outside.
I'll try to get some feedback posted when I see him for the next round of mods.

When I hit boost and the bypass closes the temps actually drop.

6700rpm with the stock valve springs? 
If so I might turn my shift points up a bit. 
I've also noticed slightly less low end torque but, the 1900 does NOT fall off like the 112 did.

Ya, i turned vvt off, I wanted just one timing table to deal with. When I have more time, I'll play with them and see what happens with the drivability and charger.

I have no idea!!
I ran a 2 bar MAP sensor with the 3.4" and 3.2" pulleys which were 5psi and 6.3psi respectively. I had to remove the 2 bar MAP sensor because of tuning issues with it but, going off of the other two pulleys I'm ***UMING that the 2.8" is around 9psi.

I don't like turning the engine that high either, with stock springs, but hey, it hasn't blown up and it's still pulling and no valve float, so it's good.
