I think my numbers are inflated by a boost leak.. I just haven't gotten around to making a 3" boost leak tester just yet. =P

35lb/min via dsm link w/ evo 3 16g at 20 psi
53.9lbs/min::: 22.5psi:::93 octane:::: 21degrees of timing....on a t72
37 lbs/min @ 19 psi on a 50 trim with stock 6 bolt long block (2.73s 70-90 time).
Added hks 272s and i am now seeing 40 lbs/min at the same boost level.
47lbs/min @ 21psi. GT3561 w/ Cams on pump gas and stock long block.
Here is a snapshot of my DSMlink log from this past Oct at Englishtown. 27psi on a PTE GT3255E internally gated, 93 octane, 50/50 H2O/Meth injection, Calibrated 3"GM mas, FP2 cams, Ported head and 1mm oversized valves. AEMWB reads 11.6:1 to 12.0:1 most of the run due to a voltage varience in the 1g ecu. Actual WB A/F readings were in the mid to low 10's the whole run. As you can see I have maxed out my 750cc injectors or the walbro 255 in the tank. I have a set of 950's for the '07 season and might be adding a Bosh pump as well.

TJ, Im sure you have read in many posts here on tuners, that every car is different when it comes to what timing and A/F is best. I have tried leaning out the fuel and as soon as I get close to 11:1 the car starts knocking more than I would like to see.. My car likes a 10.5:1 A/F and I have to live with it for now. My car also likes lower peak timing, I tried upping the timing to 16* above 6000rpm and the knock returns. Im not complaining, in the log posted above I trapped 112mph, not to bad for a 3450lb AWD automatic.
