Thanks jungle! Indeed the information that MTM boxes need to be recoded when bought used is very much untrue! Especially when it comes from the same engine or car model. I was informed the boxes would not work without recoding by certain companies which seems untrue now. Also the previous dyno of 285bhp was from the previous owner jungle and that was WHP. Unfortunately due to lack of time I was unable to do a baseline, which I might do now to get a clear difference in performance.
