I got Superchipped and I love it!
Loving the throttle response & low down torque. Looks like I won’t require a SprintBooster at all! This tune is so much better than my ageing stock R36. I was contemplating between only a SprintBooster or the tune (only $300 more), I’ve decided on a more long term solution of the tune.

I noticed the gear changes is a lot smoother and always in the right gear where torque is readily available. Also noticed the throttle to be a lot more linear and not with a sudden surge in torque after a short lag when you put your foot down.

So much more driveable in comparison! Should have gotten this a long time ago.
Of course these are just my opinion & experience.
