So i got my CP-E DP installed last night and love it. Everything was going great about about 50 miles later. . . CEL. Obviously it's just the o2 sensor. Anyone know how to quickly (and easily) fix this? Thanks all.
 
Disappointing, no doubt, since the CP-e isn't exactly the cheapest alternative. Call up CP-e and they'll probably know what size defouler to use.

Corksport adjusted the size of defouler used to eliminate the occasional CEL when using their first defouler, which was longer. Hence, zippo CELs on my newer version. Hopefully Cp-e has a clue in your case, as well.
 
Called CP-E and was told to reset the CEL and check for leaks.. . . i'm glad they told me that because I would have NEVER thought of checking that (sarcasm).
 
interested... I have the TXS catless DP and I just started throwing a CEL( about 500 miles) P0421 Cat warm up? Looking for fix also.
 
i had the turbo xs dp/rp set up. to fic the cel i just went to a local tuner shop and picked up a defowler for like $4. i think their really for spark plugs, but all u gotta do is drill them out a nit so that your o2 fits, and bolt it on. cel solved =]
