I got EFIlive Flashscan and played with the tune last week. I could feel a noticable SOTP gain in power, so I decided to go the truck dynoed again. Unfortunately my scanner is gone now and I cant scan the sheet for you guys, but I will try and take a picture of it and post it up.

Before tune
SAE Numbers:
343.4 rwhp
364.6 rwtq

After Tune
SAE Numbers:
372.2 rwhp
390.1 rwtq

Actual Numbers:
379.6 rwhp
397.8 rwtq

Thanks Brian
It was on a Dyno-Jet. It's the same dyno I have been going to.

 

Right on.....hey check your PM's

It is nice to see a 37 rwhp gain from the tune! I bet there is more in it

 

Great gains.

Stock pulley? How much timing did you end up with?

 

Stock pulley. Not sure where the timing is.
