Couple thoughts...

Something we discussed at one of our FBI bull sessions** was pulling the plenum and blocking off the secondary ports and shutting off the "Full Power" switch. This essentially reverts the mods to stock and keeps the secondaries from being activated, depending on the chip calibration. (Depending on the circumstances of the mods and calibration, a special calibration (primaries only) might be one way to assure the car is compliant.)
Also, mixing fuel for a 15% alcohol ratio has helped some of the cammed motors; one LT5 and a few pushrod motors too that I've read about recently.

**(Next BS session is tonight 6/24 at Home Run Pizza, if anyone is interested (see East Central Region page - look for Bloomington Gold threads)
