I just got back from 3 hours at the dyno, and to say I'm pissed off would be an understatement.

These are my dyno results (no scanner at home). All SAE corrected.

1: 200.81/165.35
2: 200.99/170.15
3: 189.16/167.85
4: 192.47/172.09
5: 187.33/167.89
6: 184.43/168.99
7: 187.96/168.48
8: 186.97/175.27

Mods to 6MT 2004 TSX:
Injen short-ram intake, TopSpeed header, RT cat, Tanabe MT catback, CT Supercharger

Considering I was expecting to hit around 245/185, this is mind-blowingly bad.

Things we checked:
- belt tension is correct (1/2" drop from top of tensioner mechanism to top of spring perch, per CT-E instructions)
- proper boost is being achieved - we connected a boost gauge and the car is hitting 5-6psi at WOT
- a/f - this seems fine, car's getting into the 11's under WOT
- timing - is not going past 19-20, at most. This is a problem - DAYTA was with me, and said that during his baseline supercharger dyno, his TSX was hitting 21-22 at the high end.

The shop owner and I took a spin in my car, and immediately after leaving his shop, a CEL is thrown. I pulled the code, and it's P0325. Someone googled it, and found a thread here on AZine which identifies it as the knock sensor circuit. The thread went on to discuss that the knock sensor has very frail/flimsy wiring that is sensitive to heat.

What I'm hoping:
That the knock sensor has been going bad for a while and that today it breathed its last breath, and that a new knock sensor will cure all of my woes. If not, I'm going to have to get a compression test done, because I don't know what else it could be.

ANYONE with input here, please let me know. I feel like I just got kicked in the stomach. I'm so bummed out.
