Sorry to hear, when we used to have those tests here we would have folks come in with there mini vans etc to work and fill up there cars with our Sunoco 110 octane LEADED racing gas and then pass the test! I am talking about 10 years ago since we had the test here.

I know I took my 340 challenger through one time with a huge racing cam on straight 110 leaded race gas and it passed the first time.

Was your car really hot and blown out on the highway right before the test? They used to say that would help in some cases.
