Similarly, a tune will not necessarily give you any better throttle response but definitely gives more power and torque. Moreover, M button remains functional with Evolve tune which means that you can always use it with or without the tune.
Coz 'Stock (without M button pressed)' has the dreaded turbo lag and with the 'M pressed' hardly any.
So was just wondering if the Evolve tune (without M pressed) whether there's the same turbo lag.
