I Mick, I thought you used Xspurt injectors with your customers cars? Did you have somes issues, or just picked up distribution of ID? Correct me if I am wrong, but both Xspurts and ID's are modified Bosch injectors, how could any of them be a copy of each other? Keen to hear your feed back as I haven't heard anyone having any issues with the Xspurts, I know more people using these over ID's. Cheers Ben
