Also, I waited more than a month to get the car dyno'd. It took the car weeks to really learn the tune. IMO, just one or two tanks of gas really isn't enough. And it seems to learn faster if you do long pulls in each gear, I don't think just cruising doesn't really do much for it.
That can't be whp? I find it hard to believe 235whp even with 3-stage and tune. Unless that dyno is even more "friendlier" than dynojet. I am gauging on the "heartbreak" mustang dyno which tends to be more realistic.
And why is there such a large discrepancy in speed and rpm in our baseline vs AA?
