Thanks man.
I went to HP Logic today to get the car checked out (it has been a good while since I got tuned). Staff were very friendly as usual and got to check out the record holder for worlds fastest porsche. Eddie Bello's 1157whp 964 Turbo...it did a quick low boost run and made 760whp at 17psi....wow.
We put my Z on the dyno and it made almost the exact amount of power it did when Jack first tuned it, however he did take out a little fuel in the low-mid end and I gained +25hp and +25tq across the midrange. Now fuel trim is spot on and the car feels smoother and even more drivable than before. Would, as always, recommend Jack to tune your car if you're anywhere near Florida.
Very simple, no bs Dyno sheet. This is on a Mustang Dyno where I dynoed 256whp stock. (144whp GAIN) Came out to 390WHP and 290WTQ @9psi.
