Default Cel hell.
17963 and 16804 keep triggering the light.

Boost is set to spike to 23-24 and hold at 20-21
5.75 turns on the BM - yet I have "charge pressure max limit exceedded"

I have the 42 Draft Design downpipe with the high flow cat. I have no clue why it keeps faulting (Bank 1, Efficiency Below Threshold)

any thoughts out there?

(edited.. even though I am tossing a cel.. no limp mode. Car runs great still)

Did you put the 90 degree block on your 02 to eliminate the CEL?

Default according to evan's site.. not needed.
"Will your downpipe cause a CEL?

Street series downpipes will NOT cause a CEL. Race series downpipes will cause a CEL. The CEL can be avoided by using an angle block adaptor on the second oxygen sensor. To learn more about CEL fixes please read our Test Pipe FAQs."

Default I've got an occasional 02 sensor code - but no CEL - I just clear it....
and don't worry about it. Sounds like it's something else as well.

Default Well?...>
All set-ups are just slightly different and react differently to mods. Put one on and turn the BM down a tad..Before you wring that little K04's neck...:-)
