HP/TQ is only one variable in the equation....
One question that hasn't surfaced with this whole thing - How much weight did you shave off stock? my guess is not a "heck of a lot", but perhaps 60 lb?? You must have gained something on the dyno with the wheel/tire setup alone
To UL's point on alignment above:
Please note: I'm sporting 0.09 Total Toe-in in the rear v. your 0.50 and
-1.6 degrees of camber vs. your -2.5
(I've got comprable wheels as yours)

I was just hoping that this would put me around the 210whp area. I thought the ECU would bring up the mid-range where the exhaust manifold is obviously killing me.
I realize that my new alignment settings do bring down my numbers ...but it still doesn't merit the loss in the mid-range that I am seeing.
I assumed that since all the products were made by the same manufacturer that they would work well w/ each other - which is obviously not the case in this situation. Like I said earlier, I am not trying to downgrade Spoon Sports, I'm just sharing the results that I have personally seen.
I also realize that the difference in the days (as far as correction factor) are not in my favor - but this was the best I was able to do and I tried to be detailed as possible.
My main gripe is the loss in the mid-range ...because that is what is needed from a roadcourse point of view, which I had assumed Spoon Sports would really hit this area (mid-range power) since they work w/ so many different racing programs. I guess my expectations were wrong.
Also - concerning the air intake duct - I had a blower aimed at it during all my runs (wind speed approx. 40mph) so I did have a source of incoming air.
Thanks for reading.

Hey Chris,
Sorry to hear about the lackluster performance.
A few things I've notived on my car were:
Taking out the baffles in the airbox increased hp and torque figures.
Adding a Speed(Spoon) throttle body increased hp by about 4hp.
Replacing the CAT w/ a Spoon test pipe, however, DECREASED hp and torque everywhere.

Did it ever occur to anyone that the factory engineers might have pretty much milked all they could from the engine? BMW did with the Z8. Drive it and love it. Like I've said before; When the green flag drops.....

I wonder how much of an effect the difference in tire pressure had on the two runs. On the baseline run, it was 35 psi....on the run with all the Spoon mods, it was 32 psi. I don't know if the increase in rolling resistance is substantial, but at the very least it's a factor.
