I have thought about it, but most shops around here charge a fair amount for a dyno run only.... plus there are liabilities that some don't want to deal with.
I can't say how much a dyno-run would cost... but I would be interested to see it as well. my FP3 on my 14SGS made a WORLD of difference and didn't need a dyno to prove it to me.
If you are a 'numbers chaser'... not saying you are... the FP3 is not the BEST CHOICE over other tuners that require a dyno where they tinker with the tables several times to achieve top performance.
Curiosity sucks sometimes...LOL! I would do it with my 14SGS... but I'm not paying for it...
