I haven't been able to get the new dyno sheet for the GN, but this is the one that he got when he bought it from the previous owner. This was on race gas. He now runs meth so he runs a similar boost level, but on pump gas. This dyno is of the uncorrected numbers, but he said his new dyno sheet is ver similar, just about 10 hp higher and a little more torque.

Thats the same shop thats done all the work on my brothers its about 30 minutes from my house. They have gotten pretty bad lately with there work though(ALL GN, typhoon and scylone work). Somethin isnt right if hes only make that kinda power with a 72mm. My brother made a little over 400 with a 57mm on lower boost like 22-23.

The previous owner had the work done, probably about 5 years ago or more. The shop that retuned it and installed the meth kit is up here in CT. The tuner at this shop said that with a bigger exhaust, well matched converter, and 67mm ball bearing turbo, the car would probably make 600 without a problem. From my understanding, it's all in the total combination, not just the size of the turbo, but I could be wrong since I know nothing about turbos. Beyond that I don't know what else to tell you.
