Default FS 2005 STi

I own a 2003 bugeye (E85) with a complete 2005 Sti swap, it’s running speed density. The code first popped up in October when I was driving around town, I was stuck for hours in limp mode trying to reset it until it finally reseted and I got a couple miles down the rode til it came back on, I couldn’t go up any hills and couldn’t go over 15 mph so it was a b**** to get home. I get p2109 everytime and once a week the codes are gone, my car lets me start it for about 5 mins(runs totally normal) then the code randomly comes on, puts her back into limp mode and I have a p2109 and a p0638, the p0638 resets when I reset the ecu but the p2109 is a hard code. I’ve tried replacing the throttle body, ecu, relays, and a whole new throttle pedal, I’ve checked my alternator(looks fine), I installed a iwire grounding kit thinking it would do something. Around December I took it to one shop and they replace a wire from the tps to the ecu it fixed it for about a week or two, then I went to another shop they replaced the throttle body and dyno-d it to a lower horsepower, better for a daily. About a month later code has come on and ever since won’t go away, I’ve been hacking at this for months, it has just cost me too much and I’m sad to say I might have to let it go. Open to trades!!!
