Getting dyno'ed today...
So we'll see how she's fairing. Did the ECU throttle reset just now, made sure the filters are clean. Everything seems to be in order. Having a good friend of mine do the dyno at his shop.
I'll let you know the results later.

Import Auto Pros....and the results were disappointing, and leave me with more questions. 
Used a Dynomite dyno machine. The best it came out with was an embarrasing 292.5 WHP, and 310.8 TQ. Doesn't make any sense. I keep hearing from everyone I should be hitting 320-330hp w/my mods. The only thing I could think of is that the dealership screwed up my tune when they replaced the intercooler and cleaned out the engine. I'm going to verify it tomorrow and see if the tune is in place. If it is...then that's what it is. If not, I'll be real pissed at the reflash, but happy because it means I had my victory w/less power.
On that note, the owner of the shop and I talked about the kill before the numbers were ran. After he ran them, he did say that he believed me. Albeit I probably won by a blinker's length, but he believed the run was a victory. Which was true. I barely won. He basically said the torque output is enough and over a wide powerband, which would help out considerably more than sheer horsepower.
An additional note, my buddy in his Sentra got it dyno'ed, and came out at 146hp at the wheels, while at the crank, we estimate 185. Based off of that, that's a 22% drivetrain loss on a front-wheel drive, manual transmission. It makes me wonder a lot what that equates to on my car.
Any help out there?

the 320-330whp number is on a dynojet. It reads higher then a dyno dynamics, or mustang dyno.
On a dynojet, fwd usually loses around 15% on average give or take depending on if its a auto or manual.

If yours can pull an M6, good on you. It’ll beat those that it’s able during any given contest.
Never quite understood why one feels compelled to prove anything to others on automotive forums.
With the myriad variables involved, dyno data (recorded on the same treadmill) is useful for before & after modification validation and mixture strength verification - nothing more, IMHO. Who races dynamometers?
Have surprised a few gentlemen who were piloting ostensibly “faster” machines during off-highway encounters.
Helps to keep the hobby interesting.

I'm thinking it's the tune. LET/Eurocharged did mine and I think it's more aggresive than the PowerChips tune- just my opinion. Is the IC pump in good condition?
