Finally took the initial plunge and got a JB4 and some air filters...decided to purchase from Mike at ExtremePowerHouse.com because of his presence and help on these forums. Before I even ordered or talked to the guy I always seemed to find him helping somebody and supporting members on the forum.
Then I place the order and get a call, and was surprised at how responsive and fast he was. We changed a few things on the order over the phone (he called me instantly by the way), he was super friendly and helpful...and helped me trouble shoot an issue right away. The issue was I didn't read the instructions properly! my fault. But he tried hard anyways and we figured it out.
Thanks Mike - I highly recommend
