Went to Blakes dyno on monday night, Best I could get was 393 to the wheels. Doug at Bama Chips tuned it and installed a cold air intake and smaller pulley. Found out only getting 6.9 lbs. of boost, belt was slipping on the top side. I also was running out of fuel up top, to much for stock pump. Pulley was advertised as 7 to 9 lbs. also added the bigger idler, was no help. Anyone got any suggestions on how to stop or minimize slippage? It's a roushcharger. Also where can I get a boosta pump? Another question, any suggestions on how to get rid of some of the cement blocks weighting down the car. It's an 05GT? Oh yeah, forgot what the torque was, somewhere in the mid 300s
