Hey guys I just had my car tuned by a well known tuner. Question is I've been getting ever since his first flash a tcs light on as soon as you start it and will intermittently just go out all on its own. My car did come with traction control and was working perfectly fine up to the tune. What could this be? Does anyone have any ideas?


Also my car has been setting a map sensor faulty code causing the (mil) check engine light to come on. What could this be? Does anyone have any ideas?

Here is a list of mods

loose wires... loose MAP sensor...

check the wiring harness under the car and the plug that goes into the rearend/axle for the ABS/TCS. one time I have had my light come on from being on the dyno and also the dyno straps pulled one of my wires out
