Just got back from Dyno. I have a Diablo chip, 8lb lower pulley, and K&N filter.

331 hp
438 tq

The guy who did the dyno said they use an 18% correction factor for driveline loss so........390hp. I thought it might put down more but I'm real happy......now I have to get to the track b/c those numbers beat dynos anyday. BTW, had an air/fuel run as well and it was running fat at 10.8-11.2. If I re-chip it to around 12.5 I should pick up around 15-20 ponies but it will not be as safe.

 

DropTop, If your using a Dynojet dyno, I would say that your rwhp is more like 390. Stock L's are pulling 330-340. Of course we all know that Dynojet dynos tend to read a little high.

 

Drop-Top,

I read on this forum or one of the other L forum, that the optimal air/fuel ratio was 11.7-11.8 to 1 at Wide Open Throttle. You might want to do a search and see.
