| Like I said, that does not represent a decent sample size. I would not rate any turbo I sold by one dyno run. By this chart:
 By that dyno he was running 24 psi and 21 degrees of base timing. I am not saying this is impossible, just not likely for many people. You read WAY to much into what others say. When a customer asks how quick can they get their stock turbo car to go, I tell them low 12s is great even though we know of 2 11.6x stock turbo cars. I guess it is my science background, but I always see things as a bell curve, were most people fall into the middle of the distribution. Now Greg, Seb and other tuners have shown to be able to push the upper limits of the distribution, the average person will be disappointed if you tell them to expect to be at the upper end of the distribution. That goes against everything that statistics teaches us. To summarize, I give power predictions based on the average set-up, you seem to prefer to want everyone to expect to be in the upper end of the distribution. I am not knocking the JWT turbos, but I do not want a customer coming back mad because they did not make the HP that I claimed.

That is still only 1 over 500 rwhp. -
