Some impressive results
How would this go in terms of adding further mods down the track? Eg if did the tune alone first, then added a DP, would it need re-tuning to accommodate or is it mainly a generic tune for the N55?
If going down more serious modification route such as Pure Turbo upgrade, would one still require a piggyback such as JB4?
Has definitely got my interest (EWG M135i) but I'm in Perth and not yet 100% decided on what route I want to take with mods yet..
