2010 FLSTC is going in for a stage 1 today (rush slip-ons, SERT). The whole EFI tuning thing seems too much like a black box to me, especially if you are handing your bike over to the dealer. I hear lots of talk about how hard it is to get it right, few techs do it well, etc. I feel like its easy for the dealer to slap the stock HD map for my combo on it, make sure it doesn't sputter, and declare victory (and charge me 3 hours for dyno time which actually took 1). My question is this - what should I ask of the dealer so that I can be reasonably sure that some care and expertise were applied to the bike - before/after dyno graphs? Anything else?
