Default New Series I Owner...

Hi!

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.

I'll move this to Performance for you. You'll get better exposure in that forum.

To run a 2.5" on a 94/95 L67, you need a good free-flowing intake, 180 thermostat, and at least replace your catalytic converter. Ported exhaust manifolds would be preferred.

Your Power Tuner will not work for it, but you should have the ability to scan for KR. There are no 'off the shelf' PCM'*, but GMtuners should be able to burn you one if you know exactly what you want. They make no assumptions for you.

Do I need a PCM tray when I do an intake?, or is the PCM somewhere special? Thanks,

That long filter will make it hard to seal, and it needs to be farther from the engine and closer to the headlight. The accordian tube is killing you unless it'* only hiding part of the pipe? If the incoming air touches that, you're defeating the purpose of the intake, which is to creat laminar flow and higher velocity.

It is hiding a large portion of the tubing, so is the filter. I did this due to the similarity in my Thrasher intake. The only problem is that I have no airbox...I will extend the filter to the max towards the headlight and see what I can find. I will also relocate my IAT sensor into the filter. This is the size filter from the Thrasher for the GTP'*, I had an extra one left over...

You want a smooth-walled pipe from the filter all the way to the throttle body. No OEM accordian.
