today I failed due to high NOX, here are the numbers.
vechicle state standard
HC 0.78 1.60 PASS
CO 4.34 15.00 PASS
NOX 2.96 2.50 FAIL
I am running a TT emissions chip set at 38psi line off, new cat all egr ports welded, new motor with 224/224cam 50psi injectors, ported heads, 6152 turbo. The coolant temp was at about 198 to 201 for the test and outside air temp about 101 degrees. I had a full tank of 91 octane gas, my question is would d-natured alcohol do the trick or something else? And if so how much to add to the tank, fuul or empty? any help would be greatly appreciated.
