Yesterday it threw another cat code. Probably hasn't even seen 500kms on this one! The mechanic says he can install some kind of fooler for it that retains the cat, otherwise maybe a test pipe?

What does this car really need to run no codes with the chip?

dude...no emissions testing in alberta = go catless A.S.A.P. and get tuned to eliminate the CEL.
