That's my spark table. Before you say anything about its aggressiveness I'm still running NA. I made it aggressive in order to regain some power that was lost in the installation of the MS, which I will get to next.
This car, with the MS, probably has on the best part of 80rwhp. If that. It also accelerates slowly and roughly. Funny thing is though, it runs beautifully. Idle hoovers ~900-1,000rpms with no backfirage. Timing was set with a timing light.
Here's a datalog from hard acceleration:

Any advise?
Oh, and one more thing: I've narrowed down the lack of power to the MS. I reinstalled the stock computer, and bam, it ran perfectly.

I was actually thinking pull 12°, tune fuel, and then maybe start thinking about putting a little bit timing back in on a dyno. If the engine is still in one piece.
Waaayyy too much advance.
