Default Idle/overall starting and Rich Problems? help needed, and NWS

Alright I recently boosted my d16z6. and have serious issues and I am now lost...(Long post in detail)

Head: stock
Bottom End: bored .020 over, Eagle Rods, JE 75.5mm pistons 9.0-1 cr, .051 commetic HG, clevite bearings, balanced rotating assembly.
Turbo stuff: DSM blue top injectors, DSM 1G BOV, DSM 2G T25, HF manifold, Stock wastegate, honda oem resistor box
ECU: M/T chipped P28 with ------------- custom basemap

So when i first got the car all together it ran pretty damn well! Stock internal wastegate and I was hitting 15psi straight no creep/spikes...no big deal although im on stock MAP sensor(my thoughts as to the issue). While cruising the AFR's were pretty much right on the money at around 14.4-14.8 and WOT was around 13.2 AFR. It would fall on its face at 4k-rpm and vtec crossover, alright thats the tune fine. And no CEL

It ran that well for aprx. 1.5 days and wasnt able to get to tuning yet. It broke down wouldn't start. got it home and it started then would break down intermitantly and now with a CEL...so i switched the stock map sensor with a spare i had kicking around that worked when taken off, nothing...try to run the CEL I now have and no dice, the light doesnt blink when the 2-pin pig tail is jumped..light stays solid. When it would start it was wicked rich and idle'd like ----.

Now it will no longer start, and has zero spark...replaced the dizzy. get it working but the car still runs very rich, and would now start again...for a handful of times...Won't start anymore...

Ok, ECU ---- the bed so i grab my M/T P06 unchipped and can get the car to start everytime with just a lil bit of throttle, the idle is smoother and its running a lil less rich, but still horrible and the car will stall out if you're off the throttle...this lead me to believe my P28 is junk. So chipping/converting the P06 it is.

This brings us to a few minutes ago...plug the chipped/converted p06 in and won't start. give it some gas and it'll start. The car still runs very rich and idle is worse now than when running on the unchipped p06, while still needing the throttle to be applied or else it will stall out.

So now originally my thought was the MAP sensor being junk for seeing too much boost, and that resulting in my issue. Then figured it to be the ECU. Now I'm back to thinking that the MAP sensor has something to do with it because what else would throw a CEL with what I have changed? I will be picking up a 3-bar map regardless tomorrow afternoon if all goes accordingly.

So whats wrong with my car? lol al help/ideas are greatly appreciated! thanx -Jeff

And your reward for helping/reading this long *** post:
