Anyone else experience that? Would i need a 02 fix?

 

You maybe the first one to note a CEL on the 06 but can't say for sure. Don't recall anyone else with the problem. I guess you'll have to do the typical TP fix. Strange.
I've had the Berk HFC for over a year now on my '06 and nary a CEL ever.

 

I have the berk 70mm hfc, no cel here. You sure you didn't damage the sensor?

 

I have a low cat. efficiency code on my 06 as well. This was prior to boost. I havent seen it since I went Kpro. I would add an 02 sim and see if that fixes it

 

add a a cel fix. the ones that usually comes with a test pipe, that is what i used.

 

i'll try the cel fix thxs. Didnt think i would need the cel fix with a hfc...

anyone try the Blox cel fix?

 

Does the 70mm version fit with stock header and stock exhaust?
Or only the 63mm version ?
