HappyJam Posted September 12, 2017 Share Posted September 12, 2017 Hello all, Not something I'm definitely interested in doing, just wondering really whether it's possible. I have Mk7.5 Fiesta ST-Line since brand new from January 2017. Having a look on the ford website at accessories, it seems they offer a mountune upgrade for the 1.0l ecoboost engines, but only for the 125ps version, which takes it up to 135ps. I would assume that as this is on the ford website, this would also keep your warranty on the vehicle in tact. My question is, as I can't seem to find anything, does anybody know if there is a moutnune upgrade for the 140ps version that also keeps the warranty on the vehicle in tact? I also really love the mountune grill badge and kind of want it on my car, although it would be silly to have that without actually having a mountune upgrade!

ThaiFiesta Posted September 12, 2017 Share Posted September 12, 2017 There is no upgrade kit listed for the 140PS. Their MR165 is not completely warranty friendly https://www.mountunestore.com/collections/mk7-fiesta-1-0t/products/fiesta-b299fox-mr165-power-upgrade-kit?variant=1263939724 You could however fit components from the kit that may slightly inprove sound and throttle response and engine "breathability" without affecting your warranty, such as air box, primary and and secondary hoses, and charge pipe upgrade kit.
