Took the car up to AMS Performance in Chicago last Friday. I had AMS replace some leaking seals, and a wideband A/R gauge for safety and retune the car.
AMS last tuned the car in mid 2008, and there's been some parts switching so an updated tune was in order. I also wanted to verify the boost leaks were the only reason my traqmate logs showed me down on power and not something more severe.
Results = Yummy! (Vid below.)
Nearly 360whp / 380wtq on their Mustang Dyno in cold 20 degree Chicago weather. That's nearly 470hp if measured at the crank. I think that'll pull nicely.
Huge thanks to the team at AMS for taking care of me including Dan & Eric up front and Chris for the tune.
