Took the new 3 liter to the dyno last night

Looking good. If memory serves, I made 340rwhp at 13psi at one point with my vr5 3.0L set up -- so this doesn't look terrible to me. The VR chip board provided a near perfect tune in my case, however -- I really just had to add a smidge across the board to get a good tune, then just a few tweaks here and there to optimize off-boost driveability. So, if your base tune is the VR chip board, that A/f graph is trying to tell you something -- boost leak perhaps? What pistons are in that motor? The Andial/Mahle's make for pretty high compression with a 2.7 head, so probably best not to push the boost higher on pump gas.

If you put a cup of hot coffee by the dyno air temp sensor you can pick up at least 20hp.
As I am sure everybody has heard before - you can’t accurately compare one dyno to another – even from the same manufacturer.

Josh said he was adjusting fuel only - not timing. Is that the proper order to "tune" a car on the dyno? Dial in your AFR first, then tweak your timing to get the max HP?

Sweet! Sounds like you have some good news! I have another buddy that would probably like to get his car dynoed as well. How do your Thursday evenings usually look?
