just follow this unitl your at around 11.5:1, but if your o2 reading was from a tail pipe sniffer it will be a little off anyways.

I got back from the dyno today; I paid for one hour at the dyno and I did the tuning myself. This is my first time ever tuning a car. I got 174whp 138 tq. Still at 10 psi, I know I can do better. I advanced the timing a bit at the distributor and I lost almost 7whp, I put it back to where it was before.

I think that retarding the timing at the distributor will give me more power. What do you guys think?

if your runing uber your timing at the dizzy should be stock 16 degrees.

those power numbers are still pretty weak for 10psi on that setup. Don't advance the timing at the dizzy. It needs to be advanced in the maps instead. Thats what uberdata is for!

Considering I have a 2 1/4 down pipe + 2 1/4 exhaust with a resonator that stops all the flow from the turbo, I think the numers are fine. I would like to test on the dyno again to tune down low and retard the distributor a bit to see how the car reacts.

what the hell is all this talk about retarding the dizzy, are you running the afc hack or something :P was the csv file in the first post from your first dyno or the second one when you netted 175? post up your most recent data log from the tune you are running right now, and post up your current tune, i may be able to 'bless' it :P

jesus, just get someone w/ a wideband and a laptop to tune you ---- instead of paying to back to the dyno 4 or 5 times
