Default 272whp and 292tq!!!

Hey,
I am new (sort of) to the RMIC, at least I havent posted here in a long time. Just got my wrx dyno tuned over at Mac Autosports and after a few runs laid down 272.3 whp and 292.4 torque. I am running Stage 4 with a FMIC at about 19psi. It was doing great on the dyno, knocking slightly from 4200-4700 but we thought we had it fixed...then I drive back to Boulder and knock knock knock from 4200-4700. I need to go back and have them play with the timing, as its basically still on the stock ECU. It seems to only be knocking with a lot of load on the car when it running relatively hot, as it was only knocking on the highway in 4th and 5th gears. I stopped to get dinner, went for a drive again and 1-3 gears the car didnt knock once even at 42-4700 (didnt get into 4th or 5th). Either way, I will go back and play with timing...I am very happy with the results even with a slight knock. The tune brought my peak torque from 243-->292, so it was well worht it. Paid $140 for an hour tune. Good guys over there!

I didnt write the entire thing up. We had to stop tuning because I have a REALLY old utec revision (2.5B) and we couldnt get it to replay the run, so we couldnt figure out exactly where to adjust fuel and timing to eliminate knock. So, not their fault, just my lazy ass. I just need to update my software and we can adjust accordingly in like 15 minutes. PITA, but still my fault for not checking that before I went. after driving a bit tonight, it only knocks after it gets heated up, so it wont be hard to tune out, very minimal I think.

Does it still have the 272hp and 292 tq with the screeching and knocking? I hate to make it sound like a junker, but I want to see if that makes a difference?

HAHA! I conqured it today! I pulled the BOV completely apart and then redid all the FMIC piping, as well as checking all lines to the turbo. Then I did some Utec tuning and fixed my many problems. No knock, no screaching noises. Not sure if its still at 272/292, but at least its driveable again! I know if I hit the dyno again I could get it well over 300/300 as I am just butt dynoing it and logging my runs (no wideband). When we did the initial dyno tune we didnt touch the timing...I did a little bit today but I know its got some more power in there. Thanks!
