Well, finally got 'er done, and I have mixed feelings. DEFINITELY worth the coin IMO, but a tad bit disappointed. Here is the Dyno sheet..I labelled it in ink to make it more clear:
You can see not only did the Peak RWHP increase by 25/27, but looking at the curves, the gains were throughout the entire power band, not just a single digit way up at 6900 rpm That is the good. Also good was the feel of the car and the great throttle response. Actually even sounds better, but didnt get the chirps in between gears I was looking for. When I go back, gotta check to see if the shifts cant be firmed up even a bit more.
The "bad" was the fact that I figured closer to 355-360 baseling and closer to 390 after. Had a couple factors against us though.
1. Auto (actual less HP)
2. 20" rims that are a bit heavy (actual less HP)
3. The auto had to be dynoed in the 1.5:1 third gear (artificially lowered numbers). This results in about 3-5% lower numbers than a dynoed car at 1:1 (like 5th gear in MT). That would represent about 10-18 more ponies which I will probably get on the road.
Gotta try not to get too hung up on the actual number as much as the experience of driving.
Here's a couple of pics:
