Hiya. I've got a Fiat Ducato Milano that was struggling up hills, especially when full of bikes! I had the ecu remapped and now it's got loads more power but doesn't use anymore fuel, less even. Not sure what they do, some sorta computer reprogramming, it's all foreign to me, but I just know that I can get up hills with no probs now, hee. I took it to a place called Chipwizards, near Rochdale, close to Manchester.
