Do you have a good resource of the GTE harness and ECU pin outs and one for the SC4 body plugs and ECU pin outs?

Im guessing it just moving around the pins to match up to the corralating body accessories.
I don't have any pin out diagram. You might be able to get it on MKIV.com or lextreme.

seems like a pretty inaccurate reading of your power. seems like youre boosting 9psi nicely then a little before 5k rpms youre getting a bad spike to more than 15psi... where the factory boost/fuel cut it.

seems like your af is also at about 13... kinda lean.

Use the plug that come off the harness. If that does not fit just swap the alternator plug out.

Yeah, this graph was the first before I got my car tune. I got sick boost spike and along with af issues. But its been corrected. Car is running great. Loving it

Get a usdm is worth the extra money. You get more aggressive cams and 550cc fuel injectors. But overall is the condition of the engine. I can't recommend my local place because I have to exchange with them 3 different engine until I find the one with the condition I wanted.
