Hi
I'm mustang X-charger user ( 3.0" pulley)
I looking for upgrade
So I got to find 3 mod on Explorerexpress
www.explorerexpress.com
There are 3 different size of pulley 2.6 ",2.8", 3.0"
But, It has been described as to use the same boost!! & same HP (10-11 psi)
any one tell me what it is?

Unless you do the intercooled Xtreme upgrade you can't use the 2.6" pulley. With the Xtreme the 2.6 will net the same boost as the 2.8 does on the non-intercooled Xcharger because of the intercooler.

If you go to the 2.8"pulley from your 3" pulley, you need to upgrade the tune for the increased boost.
