Hi there chaps

Im considering tuning my v50 on the dyno to get around 140hk out of it. Im guessing its a tiny bit less since its gone 221k. I heard one guy mention that the anti spin didnt work quite correctly but thats the only mention of it. I suppose that's probably down to the box he used? Im curious of others opinion on it though. I dont really need a speed monster but im a racer by heart so wouldnt mind a bit more pep in the car, 140 the sweet spot for this car? . Id also love to have a gorgeous vinyl wrap which will be about the same price.
