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 feel the same as Chi-Town. I bet that once the ECU has time to adjust, the results could be different. My thought is to disconnect the battery for 30 minutes, reconnect and once driving the car for a couple tank fulls -
I just can't believe that t stock Y makes more power. It seems that the velocity would be greater with the SL55 especially with a supercharged motor needing to breathe... I could see where it would be too much volume for a N/A motor. I am installing mine when it arrives and I hope my thoughts are correct.
Shawn, thanks for a great write up. I was wondering if you were going to leave it on for a while then take it to the track?
