I was wondering if I could run a 15 ecu on a 16 yz450 without any damage ? The 15 had a little more power down low . I'm running 1 up in the rear now for gearing . I've tried mxa map for fmf exhaust but the bottom is really weak. Thanks guys

Specs and prices are online or contact a supplier. Usually $165-200 5 gallons . Liquid gold hp. Gas stations don't sell it.

I guess I'll pick up a tuner . I still have a 15 ecu that I used on my 14 that's why I asked the question . Not really interested in running race gas though I'm old and slow just want some more low end power is all

Old and slow, if you need more power from that bike , I doubt you are slow. Try. 5 gallons of good fuel, not the pump garbage.

My buddy has the same bike with stock exhaust and his is direct opposite of mine all low and signs off quick . I'm a 3rd gear corner guy (aka slow) , my 14 had really good bottom . The only reason I bought this bike was for the trick Enzo suspension , which is awesome. Race gas by us is a pita to get

Not sure of your location, vp and renegade is pretty easy to get on the east coast. They even ship, get 3 or 4 friends buy some, split shipping.
