Re: Supercharger Upgrade
Welcome to AF.
Swap SC pulleys, of course alot of us have. You'll need a special pulley removal/installation tool made for the Eaton M90 blower. With the 3.4" you can use your stock PCM module. You will need to adjust the range of the spark plugs by dropping a range or two colder just to make sure knock retard is minimized or kept in check.
I have a modular pulley system on my GTP and swap between 3.0" and 3.25" but I have all the supporting mods necessary for reliable operation.
