I would have suggested an o2 clamp but with the hesitation point being as high as it was it didn't seem like that could be it. You don't happen to use the stock DP & wastegate setting do you?

Yeah, as much as I like Bruce's O2 clamp, I kinda figured there was no way it would fix your problem. The only time the O2 clamp comes into play is part-throttle at <4000 RPM. Did you ever get a wideband on the car? Without that, you're pretty much just shooting in the dark. If you don't get this sorted, you may find it crop up again with the eManage; you need to figure this one out first.

There is one more source, I might take out the JDM Greddy Turbo kit supplied FUEL CONTROL UNIT.
It could be this unit ******* around with the car.
Please see attachment on the diagram if that make any sense.

Considering it doesn't have a ring for the disc, then I would assume 12:1
or measure it:
12:1 - 2.72"
yeah, I'd throw out the box. It has been working for tons of others to just run the FMU without any other fueling device. I thought the JDM kits didn't have a FMU at all and can only fuel for about 4-5psi tops.

at 5 psi it sounds like you have waaaay too much fuel....the fuelling setup you have with the 1.8's and afpr is enough for 8-9 psi let alone 5 psi....take it to a dyno and do a run and youll see exactly where your at insted of replacing parts and spending loads of time tinkering......when i first set up my car it was waaaaay to rich and it would cough and buck like it had dropped a cylinder until i got it on the dyno and saw the afr was under 9:1 .
