I just read that stock torque was 590 i thought it was 607 or something like that what happened?

LB7's are 520, 04.5 LLY's are 590, and the 05's are 605

I just read on gmc that the torque was 580 on the 05. I thought it was 607 but i read different. I started looking into this after i looked at the new banks product for the lly and it does not preform as well as the lb7.

The performance difference is because more can be applied to the lb7....more development time etc...the lly will have its day, its just gonna take a while.
