I also have a '92 Park Ave (Ultra, though). Tell me about your FAST chip, and the rotors (part number, for instance). Have the rotors increased either performance or decreased warping/pad wear? Can they be cut by any shop, or are they throw away parts after a little bit of runout occurs?
And the FAST chip, what all did it change? Did you get the top speed limiter removed (how fast have you gotten your N/A up to now)?
