I just bought my 2002 L and I have a JL Ramair. I just noticed today that it also has some kind of pulley it is alum looking so I think it is JL pulley how do I figure out what pound pulley it is

I measured it somewhat and it was 8 1/4 inches OD.

I can't see where a chip has been installed on the computer might have one inside>

any help would be great

 

That should be a 2lb lower pulley. If it is JL stuff on the truck then it might have a diable chip inside the comp that you cant see.
