Isnt there a recommended or a set pressure to use? I was thinking about putting the x-charger in mine also. Do you have a a/f meter?

I need 70-72 in UK at sea level to be safe, I have a base of 68 to achieve this tho. As Speedski said it all depends on what rise you getting out of your reg. Mine dont rise so good so I have to run a higher base, Im looking at getting a BEGI fmu now. This will let me get it right as it is and then when I want more boost I will be able to tune for that also. R88

The Begi is in series with the 1:1 so it can go before or after the rail.
