Has anyone given any thought to emissions, alternative injecton strategies, maybe water mist in the exhaust for nox? Combustion temperature? This subject is often neglected for several reasons, and it's a complicated situation. A lot of intelligent people are on here solving some pretty complicated problems with not much to work with, maybe we should have a thread on the subject.
There are a bunch of threads on it here. just depends what your end goal is to pass... The machine, the tests to pass in the car, or physically still be able to pass emissions nox wise.
