Proven Power Dyno Database Thread

[Jordo!]

Finally had a chance to do some tuning of VVEL!

It's a summerish spring in FL (note the conditions), so fresh baseline (at Z-Fever). I will post additional dynos and details as I think of things worth sharing...

First, this is my already otherwise maxed out uprev tuned 2011 7AT with Cobb tubes, K&N panel filters, Nismo take off exhaust and PPE LTH, SAE corrected (stingy) before and after VVEL tuning. Other than touching up AFR's to keep them the same after adjusting cam phasing, everything else is the same.

Behold!







We couldn't completely seem to dial out the small drop down low (edit: specifically between 4 and 4.5 K RPM or so) associated with the PPE headers (seemingly a resonance issue?), but made massive gains up top with VVEL tuning.



Here's the somewhat inflated STD dyno (without smoothing) for "bragging rights", as I call it...




Take away: VVEL tuning is absolutely worth it for an NA car, provided you have some serious breather mods on there, which many of us do.



BTW: If you are looking for similar results for an uprev tune/more info, shoot Martin Struk an email at rsenthalpy@gmail.com -- he travels all the time all over the US and abroad to tune, and as you can see, he is well worth it!
