Well jamsport mapped my focus and also my dads mk2 frs, the power delivery on the js400 set up is just immense! It's such a nice car to drive and Jamie is always a top bloke willing to help people out and is an honest tuner. If something's shit he will tell you rather than telling you what you want to hear. Karl Norris is extremely talented with cossies and Rst's the gunship map is out of this world to get that power surge from a standard t3 on a Cosworth is special. And as said above he has done some proper race engines that have down very well. If the car was still mine it would be having a live map from nms. But it's your car mate so your decision. Just please don't go anywhere near msd!!!
