I agree with mini. The Detwiler is the best on the market right now. Full travel (top to bottom to top again) in less than 10 seconds at full throttle. I can get you a 6" setback, 6" vertical lift for around $750.00. E-mail me with your address and I can send you a brochure.
I have a CMC with guage and power dial on my 882. Was real good for running some of the low water here in FL in the spring. After a lot of testing and finding the best performance settings, it turned out that the best setting measured exactly what I started with using the factory plate. Mine is like new, and I'll sell it for $500. BPS sells it for $790.
