2005 CTS-V LS6 Maggie Dyno Results So I finally got enough stuff swapped out and fixed up on the car since I bought it used that it was time to get a proper tune and get a baseline for future mods.
It made 476.13 RWHP and 451.56 ft-lbs @ the wheels. The Maggie was putting out 8.97psi of boost and AFR was holding at 11.6 with 17° of timing. I'm liking the nice fat and flat torque curve.
Mods are the following:
Stock LS6 (40k miles)
Bolt on MP112 Maggie kit with 2.7" front pulley. Magnavolt
1 7/8" Kooks Longtubes and cats with Corsa Cat-back
CF 1 piece DSS Driveshaft with Gforce Econo axles
Stock Diff (warrantied in 07, so unsure of which gen)
The other non engine relevant mods are in my sig.
Car drives great. I'm thinking about doing 90mm TB next with S/C Snout and a Cam/valvesprings later down the road to push it past the 500 mark and keep it civil.

Quite envious of those figures, for now I'll have to resort to frolicking around on cold, wet concrete to simulate that level of performance by getting tail happy like a fish outta water.
