I'm assuming this is auto? Did you spin the wheels at all?
It does seem slow. Wonder if the calibration is off or if your car is 'gasp' slow?! I'd expect high 4s fairly easily achievable with stage 1. A good driver with summer tires should actually be able to get 4.8-5.0 in stock form.
I would expect to run about 4.7ish with the tune. There are alot of factors to consider though. Did you happen to dyno it? I think it should be putting down 300 hp to the wheels and around 315ish tq.
