I have a 2003 f150 Harley davidson supercharged. I have put a magnaflow exhaust on my truck and a cold air intake. I want to get a supercharged pulley upgrade on it and jus wanted to know if I can just upgrade that or do I need to change other things? Also who make a good chip for it?

I got a blower pully from performance machine 936-588-3117 and put a superchip from texas tint 972-563-8468 on my 03 and it made a big difference.Hope that helps.
