Turbo 5.3L @7# = 311hp 360 tq
Well i finally dynoed the truck and was very disappointed to say the least. I was expecting at least 400rwhp. The truck feels really strong but dies at around 4k-4.5k. It was at a dyno day event and they had it set up for hp/tq vs mph instead of rpm. Also they didnt have af readings, but my wideband read around 11.5.
