Turbo xs mbc is a bleeder type boost controller, basically it creates a small boost leak in the signal line to the waste gate which could be why your getting a CEL. Wind the screw all the way in and see if your light clears. Or disconnect your battery for 10 minutes, which clears your cel for a while and get it inspected.

You can take the car to a local parts store (Autozone, ect) and have them scan the car. With the code they can tell you what the Cel is for.

But I'm willing to bet its for the BCS you removed. If you unplug it on a 2g it will throw a code. The only way to fix that would be to pick up another BCS and plug it back in. Check a local junkyard if you can.

But as Muleunit said. Unplug the Batt for 10 mins for the inspection.

Yeah Im pretty sure its from disconnecting the BCS. I disconnected it on mine and it didnt throw a cel but thats cause mines a 1G. Looks like someones taking a trip to the junkyard like ArmyGSX said.

one of my buddys is letting me borrow his...so at least i can get my inspection :yay:
