GWoody, I would say get a TST and stack em, I run mine on the 60-90 hp settings with the TST on 5/5 and the EZ on one and when I need some extra smoke kick it up to 3! My truck runs awesome now to say the least! I am very happy with it.
As for the cruise control, I just got back from a trip to southern Idaho and used my CC for 3/4 of the trip, no surging and very easy to control. I also had a run in with a new LBZ that was blowing some smoke up one of the grades but it was a definate run away when we hit the top at... . FAST!
I also netted an all time best of 20. 03 mpg (overhead said 19. 7) at 75 MPH and around 24-2500 RPM's!!! (Smarty #1, TST 5/5, EZ1). Gotta love the 4. 10's for interstates. My best other than that was 19. 3 @ 65-70 (TST 7/7 EZ1) trying to see what my truck could do in fuel mileage.
