Lets say a guy has a 2007 Ram 1500 and has to pass emission testing. Can the above possibly comply ? In California, the testing consists of a scan of the OBD2 system and a visual smoke test. If the computer shows no codes, it passes.
What kind of power increases can one expect while still being compliant? The stock rating is 345 HP.
I have 306,000 miles on mine. It runs fine but has surely lost some power. It leaks nothing but burns oil.
