Mtx tune or not?

[Windernation]

So one of my buddy want to sell me his Ecu out of his king cat with a precision 280 tune so he can retune his and run a different set up. I love the way my sled rides now I ride trees and climb only thing I would like is better throttle response for the trees and louder bov chatter. What do the reflashes all inprove, is it worth buying his ecu I don’t want to compromise reliability and chew through belts. Help me decide

I'm running cold air intake, exhaust, and stock clutching. I honestly don't see a need for anything else power wise to tight technical trees. Only thing I'm adding for next season is the elevate kit from Ice Age, and possible suspension if I can sell my QS3's

2018 MTX 153 Hurricane Bundle Dash Flash 240,,270 and 300 HP!! I don’t think you can just change ecu’s. I believe that are vin locked. Wouldn’t run pipe or intake without tune. Can lean out motor with add ons and no tune
