So a JMS remap is not worth it? Yeah I will defo try practising a few times...determined not to lose to a MINI
Depends what you are looking for. I reckon you'll notice an improved throttle response but as for performance...? Maybe a slightly better pull lower down.
I reckon if you know how to get the best start and don't muck up any gears, you'll be quicker. Just don't break your car trying!!
