Well we recieved a Tuning developments one and weve not gone off with a good start, we fitted it to the car and i drove it down to the school which is a mile away the car had no boost and hesitation. there was no reason for this but checked the fuel pump when we got home we checked the fuel pump out and basically the pump is broke!!! a spring and a cap was found in the fuel line and good knows whats gone into the fuel tank really not happy, well my partner isnt because its his car. weve tried contacting Tuning developments and all were getting is answering machine I've left my details to call me back but I've had no phone call back!!! I am actually fuming about the whole thing spending out £65 on a fuel pump, the guys no getting back to me and that we dont know what other problems it could cause with anything that could be in the fuel tank
