We built the car in 10 days for the Eurocharged track event. Since then, I ditched the 50trim for a GT3582r and at 15lbs she made 428whp on a Dyno Dynamics (506 on a DynoJet). Spent a lot of time and money trying to make it look good for Hot Import Nights in Chicago this past Saturday so I havnt had time to play with boost or the tune. The big thing needed is a higher stall torque converter to get the car off the line as I am only seeing 1lb of boost and when I roll off the brake the car bogs to 2.6 60fts and blows the drag radials off going into 2nd.
I daily drive this car....and drove it out to Ohio for Midwest SRT Nationals a few weeks back. About 2k miles on this setup and have yet to have a problem other than traction from a roll up to 90mph (yeah, tried to race my buddy Phil in his modded Viper GTS and spun the tires at 90mph downshifting to 3rd)
