I bought a 3.4in pulley from PFYC. They say the stock pulley is 3.8 in and I shouldnt have any problem swapping them out and I shouldnt need to do any other upgrades yet. Eventually I'm going to get the cold air intake and a better exhaust to open it up but I was curious if anyone has swapped pulley's yet, is it worth it, any problems, how hard was it to swap...Ect? Any help would be great. Thanks

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.
