Passed the OR DEQ tailpipe test yesterday. I didn't do anything special like change the oil or run gas cleaners before hand. All I did was put my old poston 36lb thumb wheel chip back in the car before testing, set the chip to stock and crank down the FP.
OR runs an idle testing and a dyno roller test
FP approx 38 psi
160 degree thermo
poston 3" high flow cat
EGR functional
All readings in g/min
THC 1.75 (2.00 to pass)
NOx 2.36 (3.70 to pass)
CO 13.1 (32 to pass)
CO2 683.8 (n/a)
