Cool, I just picked up a 2000 Park Ave Ultra. I do PCM tuning on it, not sure how well it is running in the quarter yet, hope to get out to the track soon on one of these cool days!
I would like to know too, just got mine last month. But it pulls pretty good with a PCM tune on it, I wouldn't doubt at ALL that if you could get traction, a PCM tune and a gutted air box could get you in the 14's.
The Parks' weigh just over 4000lbs and do not ET like the W bodies do.About .5 slower all things being equal.But I will take the weight penalty for the extra room.Mine has 153,000,still can get 29.5 mpg and has good power for a DD.I'll buy another..........:biggrin:
