MS2 Turbo M20 Low Load Runs Rough

[varg]

So is it running rough at steady state or only accel and decel? Your AE looks a little weak but the maps look fine. Check for vacuum leaks too. Hardware first always

Hey guys, I've been trying to do enough research on my own but I haven't quite gotten my issue resolved, hopefully somebody smarter than me (everyone here) can point me in the right direction.

Symptoms: Car idles relatively smooth, slight undulation in idle but nothing that didn't happen before. At cruising speed all the way to freeway speed, and even low speed in a parking lot, the car runs rough. Sputtering, rough, and overall not very well, although it still runs. Also has trouble starting most of the time (cranks longer than usual, hesitant to start). AFR's range from 11.9-14.0. Also tried leaning it out, 13-17, still sputters. However, once you step on it and the rpm's pick up, it smooths out, hits boost, and pulls very well. But at any time during that pull you let off a bit, it runs rough again. Furthermore, as I've tried to do my best at tuning, now it doesn't seem to smooth out as you WOT accelerate, it seems to run rough and not pull like before.

Specs: (hopefully I can recall everything, and list covers enough)
-M20B25
-MS2 running MS2 Extra (drove car for several months NA with MS no probs)
-50 mm temporary eBay Turbo T3/T4 (you know the crap I'm talking about)
-Externally gated tubular manifold
-2.5" SS downpipe, small turndown, no muffler
-Innovate LC-2 WB
-42 lb injectors (MS calculates 6.3 ms for req fuel, but reads around 2.5 when running)
-Stock fuel pump, spark plugs
-Replaced cap/rotor/wires <10,000 mi ago
-MSD coil
-Running around 4-5 psi
Here are the tables, which I assume are the problem purely because I've screwed with them too much. The plugs look dark and the car smells rich, so it seems like it's running rich (also based on AFR) but if I lean out the cruising speed cells and AFR jumps up to 14,15,16 etc it still runs rotten. So here are my questions for the experts:

1. I think the electrical system/fuel system can handle the requirements of the motor because everything runs great high rpm WOT pulls, but is this a false assumption?

2. Because of the fact that I've adjusted the VE tables with no real results, is it a setting in MS that I need to focus on? Such as acceleration enrichment?

This is my first turbo/MS attempt so hopefully I've included enough info and the right info. Thanks in advanced to anyone willing to sift through this and help me out, I tried to do it on my own but this tuning stuff is new and difficult to me! Let me know if there's anything else I need to add.....
