Yes whats the difference between the different kits, i notice its like 150i2 etc? How are they different from the 150i?
Did you get colder iridum sparks fitted, and are you running on fully synthetic oil, is that necessary?
Fitter said with my engine i could safely go for 75 to 100 bhp following getting to know the system with increments of 25bhp........! Imagaine that 240bhp out of my 1.8
