how many of you guys are running this setup and how much boost ya'll getting with the 3.1pulley on a regular street tune. (not sdtune)

 

I run a 3.0 pulley with many mods (check sig. & web site) and on a cold morning I have seen 13psi, self tuned with HPtuners MAF tune.

 

I had 9-9.5 psi on my old 5.3 with a MAF tune.

 

Ambient temp and elevation make a significant difference. About 1psi/18*F. I see 8-10 psi in the summer with a 3.2 pulley. It can get to 13-14 psi in winter.

 

wow thats what im seeing about 8-9.5psi, i wanna go to my 2.75pulley, with this pulley i've seeing 13psi with sdtune though, right now im running the 3.1pulley and 18*'s of timing, how much more will the 2.75 drop the timing, and still run meth injection,(washerfluid only)

 

I'm using the 3.4" pulley with a MAF tune and seeing 6~7 PSI.
Dynoed at 400RWHP. I feel my tranny is not long for this world.

 

I was good at 18* with my 2.75 pulley and meth.
