what kind of maf reading are you seeing with that 3.6 pulley? I just got my 3.4 on line and it is looking promissing. The thing hauls ***** for an old worn out 5.3!

 

ttt.. hello blackblown02

 

Hey! Here I am.

I'm seeing ~53 lb/min or ~400 gm's/sec at 5950rpm. Thats at 5000ft altitude, so I would expect to see ~60 lbs or ~490 gm's/sec at sea level without belt slip. Basically maxing the maf. Just guessing though for the sea level #'s.

Did you get the ATI brand pulley? Or a Reichard? What #'s are you seeing?

 

You won't "see" that much. Your stock maf will max out at 59.9lb/min or 454gm/s. Your PCM is capable of reading up to 512gm/s but requires a complete rescale of the tables. I max mine out fairly easy.

 

about 50lb/min, but I really haven't got it tuned yet. Still waiting on these roads to dry. ATI pulley no slip so far, but I am still shifting at only 5400. I really need to get a new tranny situation figured out.

How hard is it to rescale the tables?

 

At 5400 I see about 48 lb/min, so you probably won't peg the maf with a 6000 rpm shift point. Probably see ~56 57 lb/min.
