In the end no tuner will (or can) take the same amount of time to tweak the tune for every possible scenario as I can when doing it myself. They'd go out of business spending this much time on a single car, and I'd also be unwilling to part with my car for that long. That's why DIY/ECUFlash is such a great thing - I can tune/tweak as I go, making small incremental changes over months if need be until everything is perfect. I do very much appreciate all the work & enthusiasm the various people in the Evo "self-tuning-community" have poured into this - it's a great and wonderful thing!

Next step for me is to do the JDM MAP sensor mod so I can accurately log boost, and ...

while (tune < perfect)
... read
... learn
... tweak
... log
end

I'm sure I'll get it right eventually - after all, this stuff isn't rocket science

I always wait until the stock water temp is in the middle before getting on it, but I've noticed that my boost problems will persist until after the oil temp also rises above ~120F (50C). After that everything works as it should.

Anyway, I'm in the same boat you are. I have a WORKS tune with a pretty bad boost spike. My JDM MAP sensor arrived yesterday and I'm going to try and cure this problem for good this weekend.

I'll let you know what I find out...
