Update time, found a shop to fix the Goodyear alignment screwup. Only used Goodyear since they were close to my house and anywhere else I would have needed to tow the car. Now there is no wandering and the car tracks straight.
Now for the good stuff. I got the car tuned at LSExperts. Final numbers were about 400HP, 400 Ft/Lb torque. This would suggest about 500 HP at crank. As for how it runs, GREAT, pulls so hard at low speeds it make me light headed.
