Re: Lets hear them after the swap!

Bone stock 5.3/4L60E with 58,000 miles.

First pull was 243hp, 284tq
Best pull after tune was 266hp, 305tq.

Figuring a 20% loss with the automatic through the drive train, that equates to approximately 320hp and 366tq at the crank on an engine rated stock at 285hp and 325tq.

My shop helpers work cheap, but they are very enthusiastic about helping!
