I have 21,000+ miles on an install done at 23,000 miles.Have heard of others with far more than that.I have done over a dozen 500+ mile days,2-up with luggage.
Most recent trip was to this years bash at 2500 miles,1900 last year. I will ride it anywhere, any time.
I did not know what to expect before install,having heard every good/bad experience out there.I will say that it is a leap of faith
Less so today with more kits/knowledge out there. The fact is that you have added many variables to the bike.
Priority one is a good kit! Trekfuel's suggestion is a good one. I kept boost level low(5.8,stock comp.)+ intercooler for longevity,blow off valve(excess pressure)and a second fan.Fan is manditory with intercooler,good idea anyway.Wish I could have afforded a secondary set of injectors and electronics.FMU has been good after upgrading original wrinkled shim.
I set mine up this way so I could ride twisties and be able to get to them!(150 to 1000 miles away)
Main consideration was longevity.All depends on what you want out of a kit.I would love more boost but felt it would be a trade off to my goals.
Next is install and a custom tune,even more important than the kit!!! Leave it to an expert or get lots of help.I did my install with a friend to help with cost.I also wanted to know the ins /outs of the system firsthand for any future issues/maintence. EXPERT tune is everything. Maintence is more basically monitering everything more.tuning more often,oil ,plugs etc. Gauges are,to me, essential.
Good luck if you make the decision,lots of research helps too.
