Well, after a poor performance at the track, I needed to see if there was something wrong with the car, so on the dyno she went.

My best HP pull was 347.4 RWHP, the torque didn't get read on that pull for some reason.

After resetting the PCM and putting a Fram filter in instead of my K&N it pulled it's best torque numbers, 336.8 RWTQ. I didn't get a good HP read on this because there must have been some detonation or something, because timing got yanked and the HP and Torque just dropped like a bag of dirt, the HP only got to 336 RWHP before it fell off. It was a good 5 RWHP higher than the 347 RHWP pull all the way up until drop off, so I would have guessed it to get atleast 350 RWHP on that pull or better.

The O2's were great, 910 mv area.

The next thing that is gonna happen real soon is the cats are coming off and it's gonna be breathing nice and free I would hope to get about 350 RWHP conistantly then.

I'm going to the track again Friday to see if I can get a better time with the 12 bolt.

My best last Friday was only a 12.95@107.7mph, with a 1.881 60ft. I was VERY dissapointed, but everyone was running 3-4 MPH low and 3 tenths slow they say, so we'll see. It was probably due to the weather, we had some rain and storms the night before the race.

I'll let you all know what happens after Friday.

That all sounds pretty darn good to me. It's all relative I guess. Good luck Scott.
