I have a 97 gts (mods below), it made 412 hp and 457 tq on a roe racing tune. It was running lean near 13.3. We flashed back to stock and it put down 439 hp and 479 tq. We made 4 runs total 2 on roes map and 2 on stock. The 2 roe runs were nearly identical and the the stock runs were nearly identical. I'm goin to call roe on monday but I can't see how its possible to make 30hp and 30 tq less. The runs where in 4th gear on a dyno jet. 92 octane ill post the chart when I get home.
