I am interested in this as well. I failed emissions for NO2 on gas, but with a can of denatured alcohol in the tank the NO2 came way way under but my HC's came right up to the limit. Was able to squeak under on the second pass on my second test by 1 HC. I am using the stock tune, but the car now has SW Headers, High Flow Cats and a B&B 3" exhaust with X Pipe.
