Shawn,
Did you give your car time to adjust to the new mods? How many miles did you drive on the new setup before dyno'ing? I noticed more improvement with my intake and pulleys after several hundred miles was driven with them on the car.
BTW don't let the dyno do the talking...take her to the track and do some before and after runs. My car dyno's really low IMO but my track times tell another story.
I probably only put about 100 miles on it since I put the Y-Pipe on it. My main goal for the dyno was to get a baseline reading. I got that.
My car still isn't at 2,400 miles either - if they actually 'do' wake up.
And, I DEFINITELY will swap it out at the track next time I go to see if it helps.
For the record - your car was on a mustang dyno (which actually puts resistance on the car)...they always dyno lower. Like you said, the actual 1/4 and street performance is all that matters to me. Some people's cars are 'dyno queens'...I really don't care HOW MUCH it makes, but I like to know how much benefit I get from each mod (if any).
