i want to get some more power out of my lightning so the first thing that comes to mind is a pulley but my question is can i put a pulley on my truck without a chip or programmer?

and also what size pulley should i get? and wich one would be easier to change, the supercharger pulley or the lower pulley?

 

could you, yes
should you , no
and if you do go with a 4 lb lower

 

First off, welcome... Come visit the Michigan Lightning Owners CLub (MILOC) at
http://www.miloc.org/forum/

Also, please do not run a pulley without a chip, especially in this temperature. The chip can do a lot more than just adjust for a different sie pulley. by adding a chip alone you can have more power increase, then a pulley without a chip.

 

sweet i just registered, hopefully i can meet up with you guys sometime, i think i have the only lightning in my area and i dont know jack about them but im trying to lear...
