ahmed bajoo is one if not the best mappers in the country and anyone who tells you different is talking out of there arse , this bloke is ex borham trained and has mapped more cars than most of us have had hot dinners , still gets called away to map wrc cars etc hes basically the dogs bollocks. your in the best hands mate thats for sure . is the car in a running in peroid of 1000 miles? , what size injectors , pumps , pressure reg , valve springs , as all these will control what a safe boost level is and if there is any probs then it would make sense to keep it low. i would personally say around 18/20 psi would be a good solid boost level
