I should have mentioned in my post that I have the ScoobySport CEL mod as well and it's working like a charm.
After I installed the PDE Up-pipe and ScoobySport Turbo-back, I got a CEL. I added the ScoobySport CEL eliminator, but got a CEL back after 150 miles. I didn't read the code, so am not sure which it was.
Anyway, the car went into limp-nowhere mode at a track day and was later diagnosed as having an EGT sensor failure.
As I understand it, when you add an up-pipe, the EGT sensor gets the full blast of exhaust instead of being somewhat protected by the stock up-pipe's cat. So it often fails. This is what happened to me.
Reset your computer, then read the CEL code when it returns. Or install the 79 cent resister after unplugging the EGT sensor.
It's not a coincidence to get an EGT CEL after an up-pipe install along with the Cat efficiency CEL... it's cause & effect. Lack of Cat action triggers the Cat efficiency CEL while a failing EGT sensor triggers the EGT CEL.

daily driver conditions
ok you said your sensor went out due to the excess exhaust flow...which makes sense to me, but you also said you were at a track. so I am assuming that you were closer to redline than some others might take their car. mine's pretty much my daily driver, although i have fun once in a while. if i'm not stressing the engine as much, should I worry about the sensor?
The install is on sunday...i'll let ya'll know how it goes.
