    My 95 F355 is on the dyno right now and the tuner emailed me and sees a 25RWHP gain over the baseline he took last year before the exhaust was installed. It sure felt like a pretty big HP gain by the seat of the pants feel and now have some evidence to back it up. He is tuning the computers now and expects more gains as he changes fuel and timing. I will post them when I get some emailed to me in the next week or so.

    Sounds like an impressive gain, even if conditions were different. I expected no less from Goth's engineering.

    This is somewhat irrelevant due to a huge list of variables but the net gain is relative and impressive (assuming it didn't rise to 1000 from 975). ;)

    Depending on weather/calibration technique/tire weight and air pressure/gear used/condition of engine/gear lube viscosity/dyno brand/etc etc etc the numbers should be somewhere between 270 and 340. You can see how large the variation can be.
