Interesting. The garage that I use for emission testing did not object
to my air intake setup.

Great! I see that the '95 is allowed a max. of 68 ppm HC. My '97 is
only allowed a max. of 58 ppm HC. The garage did a "training test"
on it (in full race mode except for the oem computer replacing the
MP computer) and I'm right on the bubble with an HC reading at 58.
My CO% was 0.13 and my NO ppm was 34. Maybe, I should try
to increase the NO ppm a bit in order to reduce the HC ppm a little:-)

I'll probably get the test (that counts) done in January. Garage owner
said that I shouldn't worry ... they would get it passed. Thankfully,
I don't have to replace the 4-bbl MPI with the stock intake manifold!

Bob
P.S. Hope to see you and Norah at the Performance World show
next year ... will put up the details when they come out.
