    Default Tune an LT1 to pass emissions?

    Last year when I installed my headers and pulled the air/egr/rear O2s I had my PCM reprogrammed by Trifecta. Well it appears that Vince totally turned all of the tests OFF and was telling me there is no way on an LT1 to make the readiness monitors always show "ready" I called PCM For Less and asked about the readiness monitors and was told they tune about 50 LT1s a month and have never heard of a problem with one passing emissions, including states like New Jersey that are pretty tough. I am finding mixed stuff on this though. Anybody have a PCM For Less or any other tune and have their monitors show ready?
