Livin on a boat is snot a bad idea,, in Fl. Now, and then, I am tinkin about an after market tune. Computerized hand held with changeable tunes and able to store factory settings. I used one in the past one on a LT1 and LT3, Z28 & Vette. Worked good. Do to changes in tuners and costings, does any one in earing area recomend a brand and modle?? Stage kits?? I wood not be the 1st on the block to receive one. Seems like the R&D and releasing dates are changing fer a reason. And I am sure it's not a good one.
