I have a 2000 GTP with and intake, ubend delete, 2.5" to the y, res delete, 180 therostat, 41-932 (1 step colder AC Delco plugs) and a ZZP Power Log. My car is currently being tuned wtih a Power tuner and is awaiting a 3.4 pulley. I know most all of the things that I can do to make my Series II pretty fast.
My questions are on how to make a 95 Park Avenue Ultra run a little better? I just bought a 1995 Park Ave. w/ the series I SC. It only has 65K miles!
I am sure that there are many things different from the M90 SC cars, but I am sure that there are some similaties too.
Can the series I be tuned with a Power Tuner, are there PCM upgrades? What is required to run a 2.5" pulley on the series I. These are all questions that I have. Thanks alot guys.
