So I have a 6.0 4l80e 2wd setup and did a stock baseline back in april and got 248 whp and 274 torque. I got some pacesetter LT's and the matching Ypipe. Got around to doing an unretuned dyno and got 267 whp and 297 torque. Not bad for stock truck and just adding LT's. Cam is going in shortly and then the party starts.

this is the baseline running rich and droppin power up top

Printer was acting up and couldn't get a print out of the LT's run but is was almost identical just 20-25 higher across the board.

 

That torque increase is impressive!

 

Same dyno, similar temps/humidity etc? If so, that's a really impressive result. I've been looking at buying some Pacesetters.

 

with tune?

 

 

Baseline was done in April it was a lot cooler probably highs in the 80-90's. Pacesetter dyno run was done yesterday (7/12) and it has been over 100 for 30 something days so far. The guy that does my tuning said he wouldn't retune until outside temps come down some.

As a side note I was cheap and got the black uncoated ones. They will probably come off later and get coated.
