I just had my utec installed, how do I stop the CEL from comming on ?Uppipe and turbo-back on.

have you tried the manual cell fix? I know that you can turn them off with the AP but i dont know about Utec

Is the CEL on or is it blinking? If it's blinking, it's the UTEC telling you that you're experiencing detonation. If it's on. . get it scanned before you try to fix it with anything. You can't fix what you don't know.

Search for "P0546" (uppipe related code) and "P0420" (downpipe related code), if in fact you scan one or both of those.

You can spend about $3 at Radio Shack to get the right bits to fix both of these.
