hee hee. I am not too worried about paying to play....I have been doing that a long time before I got the FD...just now, it is escalated
A new wiring harness is probably a good thing.
As far as putting it back to stock...I have a gutted cat. I don't have a spare lying around either. I assume you mean put ALL emissions and vac lines back together stock. I really can't see having to put it ALL back...there has got to be somethings that I can leave out....of course that is still just a recipe for more problems.

well, I have the manifold off as I type. I can't find any proof of a vacuum leak anywhere. With the car running and my ear right in the area where the pressure chamber sits, I can here air whistling as it rushes by, but I assume that is just the air going past the throttle plates. This has to be an air/fuel/spark issue. I can't figure it out. With it running at idle today, it was pulling 18mmhg of vac, and smoking dark greyish out the tailpipe consistantly. Also poofing backfires out the back as well...really stumbling on a free rev and also on decel...clueless....

Holy Crap I Fixed It!!!
HOLY crap!!! I just swapped out my map sensor with a buddys whose car has been down a year and WA FREAKIN LA! I don't have ANY smoke AT ALL and it revs almost 90% smooth now! It is idling at about 800, so I will bump that to about a grand since I have the A/P removed. I know there is some fine tuning to go yet, but I am going nuts right now!!! Just goes to show that just because voltages check out, doesn't mean it is good!

Now, just to replace the plugs and fine tune the air idle screw and get it all set. Even if there is another issue that I don't know about, with the way that car was acting with the old map, I would never have found it. I am pumped!!

Well sonofabitch
Damn MAP sensor? Arrrhhhh. Well ****, glad you finally found it. I was leaning on fuel being the problem, but who would have though the damn thing would read correct at idle but be screwing up at different pressures!
Good work Trev, and now think of all the things you learned about the car that you wouldn't have if it had worked right from the start. Just trying to be optimistic after all the *** pain.
Congrats again, wish I could have been there to help, England sucks. I miss my car.
Oh, and my wife. LOL

STILL having problems!! HELP
Okay, here is the low down:
-700 miles on motor with 100-105psi all 3 faces, both rotors
-18 in/hg vac
-stock airbox, no cat, hks carbon titanium catback, dp, ported WG.
-stock ECU
-injectors clean
-TPS, MAP all check out
-ACV, emissions all removed, simplified sequential (AWS, EGR...still have double throttle though)
-only CEL is for the AWS. I have a resistor in the solenoid plug on the rack, but the actual harness plug for the AWS valve is just dangling...that is why I think the code is there
First:
On a cold start, the first time I start it, it will rev to 2k, then stumble and fall down and die. I restart it and it stays running.
Second:
Free rev and free rev decel are both pretty rough. Take off on the car is very touchy and rough...bucks and jerks. Car seems somewhat smooth between 2-4k on accel in all gears
Third:
I boosted just to about 5 psi, it all the time I was in boost, the car was bucking and jerking like it didn't want to boost. Almost like a limp mode feeling. Like it was retarding or something.
Fourth:
Idle is smooth and at about 1200 rpms (need to lower that a little)
I just can't figure out why the car is so rough and won't accelerate worth a crap. Today is the first time I tried the boost. I have troubleshooted so much, so I am really at a loss.
