Default Re: Passed CA Emissions

Change the chip back to stock, if that doesnt work, take out a couple more degrees timing advance in the testing rpm range. Like previously posted, dont use octane booster. running octane booster will cause a slightly lean condition until the computer redjusts to the new fuel mixture, which will drive NOx higher.
