You and I have similar mods.
The only issues ive run across are boost creep and the stock L clutch that screams at me every time boost hits 9psi or greater. I also asked you a question in that thread, but ill post it here too.
Why didnt you do a full standalone ecu?
Also, I have a custom intake that fits a clocked td04, specifically made for the 1.8l engine, its actually pretty trick, im going to get some better pics this weekend, but i just wanted to get your thoughts on FMU and also, did you end up keeping the stock L tranny?
