I think some of you guys are screwing up your car with bad or incorrectly installed mods, and are not fessing up.

I say take off the crappy, flakey boost controller, ditch the riceboi blow off valve, install the stock diverter valve, a decent manual boost controller (bypassing the stock boost solenoid), then check the wastegate and all vacuum hoses. You'll get your boost back without some retard changing your ECU.

Also I don't think that the IX is more problematic than any other EVO models, it's just that there seem to be so many new and fresh faces buying IXs, unlike VIIIs that were bought a lot by former DSMers and others with experience with turbo and AWD cars. This does not seem to be the case with the IX. Just look at some of the questions being asked by new IX owners, I mean somebody asked why there is a bigger space inbetween 70 and 75 mph in speedo, WTF!
