I also have to go with one thing JET brought up, monitor fuel pressure at all boost levels.  We are running into a problem with a Safari Van that wouldn't run under load.  It ran fine when it idled (kinda stumbled a little but not bad) but when you hit the gas it killed.  We dismantled the throttlebody and found the regulator spring broke into 3 pieces.  I'm not saying yours is broken but maybe the pressure isn't high enough to keep up with what's needed at the higher boost levels.  I could be off the mark here, but I didn't read anything in your mods about an adjustable FPR.

I'm starting to believe it is an injector. I got it back from Mitsu, but have not had a chance to run it under high boost yet, need to buy some more 116 oct. The reason I believe it is going to be an injector is because my car is getting hard to start, and when it does fire up, it misses on a cylinder for a little while until it clears up. Also have a problem where it will idle fine with my LTFTlo will be at a good -1.0 to +1.0 range and then it starts to cut up and the LTFTlo drops to -12.5 to try lean it down. Also keeps trying to stall at a stop. I have a VPE hi flow fuel rail and 1:1 AFPR with the fuel gauge mounted on oder and am waiting for it to come in. That way I make sure the fuel pressure is set correctly. Now as far as the fuel pump keeping up, I may have to get the Walbro 255lhp or higher flow pump. Not sure which way I'm gonna go with it. Maybe a Cosmo pump. I talked to Scott at VPE about the injectors and he is going to send me out another set to try.

DSMLink is working fine. The AFC is not controlled by my laptop. The AFC was only there originally to deal with the hacked maf at idle and low speeds. Since I installed DSMLink v2, the AFC is only being used for quick glance readings while driving, no adjustments are set for fuel on it. It shows rpm, throttle position, maf frequency and compensation (which reads 0 all the time) while driving.
