whats your CR at with those, i would think with that deep of a dish it would'nt be 10.95:1?

I decided to go with the 19cc dished pistons, I had Phil (AI) deck the heads to 52 cc, had the machine shop deck the block with the pistons .006" in the hole and used .029" Impalla Head Gaskets. Final static compression 10.95:1, with a .035" quench.

I had to supply the cable and the program.Nobody has LT1edit, anywhere you go in the Phoenix area. Everyone and their mother has LS1edit, but not LT1edit.
Actually, Xtreme Motorsports has it, but their prices are sky high and the tuning is not that in depth.

Kevin,
I'm glad its together & running
. Those #'s seem pretty decent through a full 3" exhaust & whatnot. I obviously haven't seen your a/f data yet, but losing that flowmaster catback for a set of 3" duals, 4" mufflex, open headers, etc. along with the fuel would probably put you in the 425-430rw SAE / 440-450rw STD range
Hope it runs well at the track!
-Phil
EDIT: Any idea what kind of timing you're running up top? Just curious

The dyno plot on the first run was not accurate due to the wheel slipping. We bumped the AFR significantly on the second run which made decent power. The final run picked up 20-40 HP accross the RPM range over the second run. I think the link is working so you can see the difference between the second and final run.

from a Mail Order tune to Dyno tune OR was there other stuff that you did before you went to the Dyno like add Headers, bigger TB, cam etc OR was it just in the tune alone that made that much of a difference?
Just curious.

Can you post your Dynojet results with the AFR graph on the bottom. I saw in the notes that your 1st pull was 14.1 AFR at WOT. I would like to see the AFR of your final pull.
