I finally got it installed last weekend with a 55" gatorback belt. The truck seems livelier but I don't want to really get on it until I get it on the dyno again, which by the way will happen in a couple of hours. I'll post the results latter today. So far I've been less than impressed with the #'s I've been seeing. Maybe it's the 91 octane gas here in AZ., maybe not. Sal from PSP sent me a new tune after my last run of only 263/310, (lame if you ask me) I did notice a difference but how much I don't know. Any guesses on what #'s we'll see after todays run? I'm saying 320/360. What do you think?

 

What's your setup and what kind of dyno, elevation?

 

01 SCAB,4x4, 5.4, auto tranny, and a Procharger at 12# boost as of last weekend. Just got back from the dyno (Dyno Jet) and it was what I expected, too lean so they couldn't do any full pulls. Although the #'s are up, 302/356. I'll get this off the Sal for another adjustment on the AFRs then maybe we'll see some better results. The elevation in Phx. is around 1200' and the temps outside where 90* today. A bit hot for this time of year. Should be in the low 80's.

 

Mine was around 345/415 with the 12lber, so somewhere near that would be a good guess.

 

I can only hope, had it on the dyno last week and it was running lean so they couldn't do a full pull, shut it down around 4000 rpm. On the good side it showed 302/365. Sal sent me another tune so another trip to the dyno soon and we'll see where we're at. I'd be happy with the torque over 400.
