I have a Powerchip stage I tune (which does NOT remove the CEL, stage II does).
Everyone keeps saying it will come on eventually, but I doubt it at this point.
Make sure your CEL is still working. Powerchip had some problems and were turning off the CEL completely on cars regardless of wether it was stage I or II. Quick test, when you start your car the SES light should come one for 1-2 seconds, then turn off. If you don't see the SES light, then your SES light is off.
