I am not the only one online claiming this stupid mileage. I know many more see good mileage. Heck I know a guy with long track that gets upwards of 15 on trail.
Yes to stock. I have put curves and a 1.22" xt pre studded track but not until I had quite a few tankfulls through it. Still not good, could be bad flash, helix , exhaust too restrictive, etc etc. I have tried very little to improve my mileage, just secondary settings and helix shim. Did not change much with those.
I have noted all saying there's are very poky down low. Mine does not seem that way !!
Will post if dealer finds anything this Saturday whereas it is going in for the updates!!
