I noticed you were still running 850secondaries. With you wideband hooked up, running that much boost, your not leaning out? You should consider some bigger secondaries to be safe. I have the opposite setup. I run stock primaries and 1600cc secondaries and have run up to 24lbs of boost, with a 11.5.1 A/F ratio.

Ernie: I should upgrade the sec's to bigger but since 17psi is my limit I'm gonna leave it alone....@ 16psi I was seeing 78-80%duty.
At 14psi I was maxing out the stock fuel system before(95-99%)...ran 12.004 @ 117mph on completely stock fuel system.<<<<Yes, I was asking for trouble :smirk:
My A/F's @ 16psi is 11.7:1 at lower rpm and drops down to 11.2 as rpms climb up. I keep it plenty safe up there, knock levels are always low :bigthumg:
I may get my hands on Datalogit soon.....willbhe able to datalog verything.

Get a bigger map and 1300cc secondaries and see what she has before you pull a vosko. :smirk: You'll prolly pull better times on your twins then he does on his single.Even tho he keeps breaking stuff.
