I had actaully looked at them as a friend has a mountune one and I love it but opted for another focus. hope to see the rs when you get it.
The sons last one was mountuned so I'd never driven a standard one, to be honest on full pelt the standard one sits with the mountune 1, the mountune like pulls better up higher revs and kinda is lazier drive whereas in standard you drop a gear and rev it, the mountune kinda has the power in all gears, hoping the stage 2 will be something special and will feel a lot better
