My SAE numbers are 406hp and 355tq with aed e85 tune and steeda CAI. I will be returning mine to stock and taking it back to this dyno then run it with the intake and aed 93 tune and see what the actual gains are. The shop only charges 40 bucks for three pulls.
Aed is a email tune but he sends you a base tune. then you do some data logging then he makes revisions. So its close as you can get without driving to an actual dyno.
I was told by the shop owner that his dyno reads 10-12% lower than other dynojets in the area
