I put in my TS chip today and I am now gettin' a "Service Engine Soon" light that comes on. I put in my code reader and it says there are no codes. Has anybody else had this issue? It seems to run fine though, no problems at all. The light only comes on after I start it and drive it for a minute, but when you shut it off and turn it back on, the light doesn't come on until you drive it for a few min. Let me know if this is something I should be worried about or if it is just the nature of the beast...Thanks in advance!
