Hi Guys, New to this site, and new to turbo cars - please go easy!!!! I've been running around on a custom tune on a BA MkII Xr6T for a while, but need to get it services (75000ks) next week. So I attemped to flash it back to stndard/factory last night. The program seemed to upload without error messages, but when I started the car it coughed and spluttered, didn't rev and seemed to be overfuelling and generally wouldn't run. Flashed it back to the custom tune and all seemed normal again. Edit: More info Custom tune is ~320rwk on 98octane Car Mods - injectors, nizpro 1+ kit with cooler The o2 sensor is disconected with the custom tune, woudld this cause this problem if left disconected for the factory tune?? Any help is appreciated... Cheers Dave.
