Thanks to all who responded. All the info is very helpful.
I have a follow-up question. I am in the process of going BPU and was trying to make a decision on which boost gauge to buy for the clock location. I want it to match the stock instruments (Black face / green backlight). Mohd tells me the only 52 mm eletronic gauge is the Greedy which reads in kg/cm2. Although I guess I can get used to the "bar" measurement, I really was looking for a 52 mm electronic gauge with the more simple (for me) to read p.s.i. Anybody know of another gauge which fits these requirements i.e. 52mm, electronic, black face, green backlight, p.s.i.?
