in a high gear like 4th or 5th mate, start from low revs like 1500rpm and foot to the floor and keep an eye on boost gauge and the rev counter to tell you what you need to know
wel depends what boost you want to run? id go with a 0.8 bar spring and have that as low boost and 1.0 on high with an ebc, 1.2bar is the most id push on high with a hybrid tho, the sard ecu should fuel that but get it checked
