Then this chart is mislabeled, apparently.
The dyno plot on my car is an Apexi turbo kit, not Blitz.
Also, both plots seem to indicate that my set-up is holding better power on the top-end. This is why it is frustrating for me to keep looking at these comparisons.
The plot you have from me was a very conservative tune designed to carry the car through a grueling Time Attack competition. The tune itself was on 91 octane on an unopened motor. Hell, the fact that you could compete in a Time Attack shoot out with a stock, unopened motor says something about the Gen III in my book (and let's put aside the wastegate failure I had there -- during warm up, we were at least on par with the WORKS Evo and passing the Power Enterprise Supra). As a matter of fact, wasn't Brad's USCC motor also completely stock internally?
Anyway, the point is, it comes as no surprise that my car does not have the area-under-the-curve of the two you are comparing against, and that has next to nothing to do with the fact that it is a Gen III and everything to do with having a large Apexi turbo that is just coming into its power range at 17-18 psi. I would guess that the sweet spot on that turbo is 22-25 psi.
I have little doubt that with a stiffer wastegate spring, a set of cams, and some race gas, my current set-up could support 400+ whp. But then, I kind of have this general distaste for bench racing and have no such mega-power aspirations at present, so for now, let's leave it at that.
