ECU EPROM Problems

[AWDTireSmokeTsi]

I just put a Mitsubishi Specialities (stage 3 TMO) in my 95 TSi AWD and my stock boost gauge does not work at all. Also am running VERY LEAN on my A/F gauge. My car starts, but it runs lean all the time. Its not the Eprom Chip Becuase I replaced it with another Eprom Chip and its still doing the same thing???Any one wanna take a shot?

Did you have it socketed? It could be that who ever saudered the ecu could have screwed something up. I have the chip in my car and my boost guage works as the o2 voltage/air fuel. My car seems to only run lean at wide open throttle. Did you get the correct info on the clutch wire? I did not and can not use the stutterbox . But my car realy has improved exept for the leaning.
