I've got a custom Jabba map, I'm well pleased with it, I'd say it seems aggressive yet smooth right up through the rev range, throttle response is improved a lot to, you'll notice as sn as you get in your car what I mean about the throttle. My mate has driven mine and prefers the way it drives against his revo mapped S3. I think you'll be chuffed..
One piece of advice, when your car goes into Jabba make sure your running shell V-power, mike will map it to suit provided your having a custom that is...
