Okay so I have an '01 Camaro Z28 with the stock 3.42 gears. Only mods are an MS3 cam, Patriot dual valve springs, Granatelli MAF, off road TSP 1 7/8" headers, and a flowmaster exhaust.
I used the HP/TQ calculator config and was only able to come up with 350HP and 330TQ. And I'm pretty sure that's only measuring to the flywheel so...that really sucks. I followed the "BBA VE MAF and PE Tuning Procedure" guide as well and STFTs were all within +- 3 and all of the MAF calibration corrections were within +- 5 so I don't think that's the problem...could be wrong though...
I've attached the tune...maybe there is something I've missed that will jump out at you guys?
