OK... so I got the IDAs on and everything dialing in pretty good but I am getting a couple of lean spikes when going WOT. I am starting in 3rd gear at about 2000 rpm and as you can see from the log, I get a lean spike at 2800 - 3000. Help. What should I trying changing? Here are the specs.

SBF 302 motor that is a 347.
Cam is a roller tappet
L.S. Lobe Separation 112 deg
Exhaust Lift 592 w/1.6 rockers
Exhaust Duration 242
Opens 52
Close 10

Intake lift 576
Intake Duration 234
Opens 6
Close 48

Idle jets = 70
Idle Holders = 120
Idle screw 1 1/8 turn (I know this is too much but exhaust pops otherwise)
Main Jets = 175
Air corrector = 225
Emultion tube = F16
Third progression hole drilled.

Ignition is an MSD 6AL running a new MSD bullit distributor. Initial timing is 14 with total at 35.

Sorry for the long post, but I wanted to make sure I gave enough of the details.
