^^^ no, they're into the s-afc. they don't really mess around with v-tak and whatnot. hybrid may be better help for you jude. call them up, its worth a shot

Buy a wideband or hop on a dyno, taking numbers from someone else really isnt safe...
I grabbed some numbers from a guy who had a very similiar setup as me, and I added a few percentage points of fuel to each point in boost, and when I got my wideband I was still running pretty damn lean...

^ agreed. With all of your mods someone else's maps aren't going to do you a bit of good.

i messed with it today and put a boost controller on and bumped it up to 10spi and tuned from there it got better but still sluggish between 1-2500rpm

what kind of fuel pump are u using? you might just need to juice some more fuel in the range u mentioned, 0-2500,
