Dumped the fuel, refilled full tank of fresh eflex. Seemed to make it run better which was good.
Idle is still hovering around 14.5-15.2:1, which I think is excellent for id2000's which don't generally idle at stoich, especially without maf scaling. Not perfect but a damn good job by Matt and I'd like to think myself (thanks to tips from another master, tony - thank you to both of you)
Made a decision to sell the post facelift 5eat setup (see for sale section for those interested)
Going to buy another 5eat from a preface GT and depending on what happens on the dyno in the next couple of days, will either build the spare one up or replace the one in my car with the one i buy and rebuild my current one.
I know at the very least I can tune my car to 250-260atw with the current box so that's my worst case which isn't too bad until I build the spare one up right?
Once box is built I'm turning boost up - like really up
