I dont think that I did to bad on two runs with dab on 3 and hom on I ran 263.61 hp and 294.24 torque. Both runs were almost identical on the graph the torque curve went almost straight up in about 500rpm then leveled out and stayed flat all the way to redline while the hp just did a steady clime all the way to 5000rpm and then leveled out. But the thing I need help with is my air to fuel ratios. At steady throttle it was about 12.5 but once I got on it and the boost builds up the ratio goes on a steady drop all the way off the cahrt which only reads to 10 at about 5000rpm so between 3000rpm to 5000rpm it drops that much and thats with hom on without it on its even worse that that and the one run not on hom I ran 240.17 hp and 274.95 torque.
What I need to know is how can I get my air to fuel where it needs to be, would a map clamp be able to adjust it that much or would I need a safc or something else. And what would you think power wise I could expect getting those numbers where they need to be.
My other mods are K&N typhoon cold air intake, stage 2 with toys, maxfab catless downpipe and modified borla catback, msd wires with ngk iridium plugs gapped ad 35, fully built 60mm throttlebody, 180* thermostat, and I think thats about it for engine upgrades.

Thanks for any help and any opinions.

ONly runnnig 12.5psi out of a stage 2 turbo?

forgot to mention the pulls were in third gear on a dyno jet and I was boosting spike 18-19 and holding 17 -18.

from my experience you'll probablly pull better numbers in 4th seeing how its closer to 1:1 and do some hard runs before you get to the dyno so the ecu can make its adjustments before your on the dyno and cause you have a stage kit you will run very rich get an afc or some kind of fuel controler. and yes a map clamp can lower your afrs cause what your really doing with it is making the comp think your running less boost thus giving less fuel. but if you get one you need to tune it on a dyno or some sort of wideband.
