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.

Oh man, I was .2rwhp off.

In any case, sweet torque and even if there is some left on the table, I'm sure it's fun as hell!

josh , are you testing on a "loaded" dyno or an "inertia" dyno for YOUR runs and tuning?

Yup - on the way home from the dyno I "went bye" a newer VW GTI - that was fun!

Not sure - it is a Dynojet and here is a link to the company's website - http://www.dynolab.net/site/

Sounds great Josh, maybe we can meet part way and introduce the two little ones as well.

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?

And Josh, drop me a line the next time you go to see Art.
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?

Josh, next time I'm driving thru ATL, I'm dropping by! It might even be in my 951.
