The diesel performance chip that was on my D22 when I purchased it is a bit of a mystery. There is no brand or marking on the outside of the casing. From trolling the internet it appears to be an ENG-TEK in appearance, with a set of 8 pairs of pins to adjust it by moving the connector. I'll contact the suspected manufacturer but in the meantime does that sound familiar to anyone else with an ENG-TEK?
