Most not so much emission compliant. However, a tuner can add MPG and make the truck drive better without changing any emissions.

How exactly is this magic done? 3 big companies in the US would love to know how to do this. Billions of dollars are at stake! If you know how to do this, please tell us!

Ask the tuners how they do it. I just know from what I read, a tune on a stock truck adds MPG and makes it drive better.

I must have missed it, but where in that thread did it say that this truck could pass stringent EPA smog requirements for this engine with this tune on it?

Also, how long will that very expensive DPF or SCR system last with that tune on it?

GM spends 10's of millions of dollars on engine and smog research and all they have to do is hire this guy for a 100 grand a year and be good? Stupid GM! :B

It's on the internet so it must be true! :B
