I checked the code with my Accessport, it's a Exhaust Gas Temperature Sensor Malfunction, is this anything to be concerned with or should I just keep boosting on my merry way? The only other mod is a gutted uppipe which has been on for 3 months without kicking a code.

Thanks.

Could be your EGT probe going bad. You could try plugging the bung with a bolt and doing the 2.2k resistor mod and see if that fixes the condition. In any case, I'd take a look at the EGT sensor to make sure it's not cracked or something which may lead to ingestion by the turbo.

I guess I'll be redoing my upipe to get that probe out of there, Thanks for the advise.
