Here is my latest dyno graph(sorry its in B/W, but I cant get image small enough in color).

I posted the questions in PFC forum under PMI?'s

But here is a brief synopsis:
Me: intake, IC, full open 3"exhaust, HKS twinamp, 1200 secondaries boost set at .85 on PFC, but creep to max of .98, mostly in 13-14 range, rebuilt stock motor, stock turbos. 70f outside, cooldowns between runs and a fan blowing.

My A/f's are way too rich. I took fuel from PMI upper rpm ranges and finally got my A/F to register at about 10.3 but only from 5-6k rpm, then it dropped. This was my last run where I produced 317 rwhp.
Is this a good way to tune or should the fuel graph(and perhaps timing graphs) be tweaked. In otherwords, should I put my PMI back to 100% and datalogit/dyno tune. or does anyone have ideas about anything?

Also, I had my water injection working. I dynoed my first two runs(not shown) w/o water injection. There was no change w/ A/F or HP or Torque, well my torque was about 3-6 ft/lbs more w/ WI and A/F could have been affected, except everything below 10 does not register and I was below 10 all the time at upper rpm, except for my one time popping up between 5-6k.
The two last runs(w/ PMI subtraction) were the 312.7 and 317 rwhp runs.

Thx
