I agree with you on the multi port being the way to go. I know of several guys that do have problems with the Pro-jection, But mine just seems to works great. Multiport is also alot more $$$. The 900 set up that I have on my mud truck (with closed loop ) I got for $450.00. That guy sold it to me because He could never get the truck to start !!! It was on a 460 Ford truck. M1028
