TR230/224 Cam
Comp 918 Springs, TI retainers, TR Pushrods
Edit Tuning
SLP 85MM Maf
MTI Clear Airlid w/ Paper Filter
Shaner S3 Throttle Body
MAC Headers w/ ORY into Cutout
Yank PT4000 Converter

(That's all I can think of off the top of my head)
My main question is, why the dip in the middle?
Final numbers are in, 399.02 rwhp!!!

From my experience they say the spike is from the stall converter dipping because of non lock up. Not sure if I'm right, but anyone can chime in and let me know.
Flash-
The dip could be caused by a little knock. Why did they start the run at 5k?
With LS1 Edit, HP Tuners and EFI you can change your tranny settings so it won't upshift to 2nd on the dyno.
Bill, I used a different tune than the one you sent. Brent at EPP made some changes for me so I went with his file but I used some of your tranny settings.
I guess I'll have to go out and do some more logging to check for KR. I believe my timing is set to 28 in edit.
Edit: Looks like I also need to bump up my shifts too, shifting at 6300 is right at my peak power. I guess I'll have to raise that back up to 6500 or so.

I just got the gears and converter put in a few weeks ago so I'm still getting used to it. All I can say is street tires are useless!
I got a stock maf that I'm gonna try as well to see, I've heard bad things about the SLP ones before.
The A/F starts out just above 13 and ends just below 13.

Hopefully we can fill in that dip by tweaking the tune though.
