I'm at 180 WHP Dyno Dynamics numbers at 7-8 PSI at the manifold. from what folks have told me that is around 210 whp Dynojet numbers.
Try doing that on a GT2560.. ain't gunna happen.. i'm running a T3 Housing .63 A/R with an external gate so it's a bit different but shouldn't be THAT much different.
What are your plans for the car? are you planning on Autox or track time?
The only thing I might change is your exhaust housing.. switch to the smaller A/R.

am i reading this wrong? 7-8psi on a 2560 ain't gonna make 210hp on a dyno jet? i guess that means 8.99psi on a 2560 wouldn't make 246hp on a dynojet either

I have the GT2860Rs .86AR and love it. It spools up very well with the AVC-R controlling the wastegate; 5+ psi by 3,000 rpm. A little over 3,500 and it's fully spooled to 12psi.
It was spooling a little better with a heavier spring in the wastegate, but I have to run a 4 pounder until BEGI sorts out the boost creep issue I'm having.

this correction you speak of on the dynojet. is this a setting in the hardware of in the software to read it? the program i have has correction factor settings. is that it? i think it's called winpep7

Most places will tell you what correction factor they use if you ask.
What i'm not sure about is if you get the the file from the dyno if it has the correction factor embedded in the data or if it's only within the application itself.
