awesome numbers...congrats wired!
makes me really anxious now to get mine to the dyno with my mrev2 and crawford upper....with pop on standby. right now i am running a stock 06 airbox.
again, great job.

I think the ECU only learns at part-throttle. Not at WOT. I could be wrong though. Most of the tuning was done at WOT so I should be okay.
But I'll let you guys know if anything weird happens.
So far the car feels really solid. It feels REALLY Good passing people on city streets at low RPM in 3rd gear. The extra torque is kickass.

But the difference is, a turbonator adds a restriction, whereas rifling does not

Maybe you can get a spacer and rifle both of em

I will ask these guys about install prices on cams. Although with cams I'd probably best do an exhaust at the same time. Wouldn't want the extra breathing power to be restricted too much.
The nice thing about my car right now, is I can easily go back to stock configuration in a day. Take off the popcharger, 5/16" spacer, trade someone the MREV2 for their lower collector, replace cats, remove emanage (since it is plug and play thanks to the autosport harness).
And no one would be the wiser, unless they look at the gaskets or something.

Regarding the fuel-trim questions:
I have no idea how long it takes the ECU to "trim" the long term A/F correction.
But it is for sure true that it DOES affect WOT A/F too - that's the hitch with these new ECUs! Especialy with the wideband O2 sensor equipped cars. E.g. we measured 8 hp gains on '04 models with high flow cats but on a '06 modell there were no gains. Coincidence? I don't think so.

Thanks for the info.
I will definitely keep a lookout using cipher in the near future to see how the ECU responds to the extra fuel from the EU.
No CEL's or anything so far, the car feels so much more responsive now, I love it

Will do it when my Utec arrives in a couple of weeks!

The UTEC does not have this same ability to average timing from 02 sensor readouts and there is no smoothness when it pulls timing for knock, it just yanks 10-16 degrees and then dumps it all back in immediately. I have played with the settings on how much it should pull out and the max it should take out but it didnt work.
