By installing a Lane regulator you benefit from the following: A flattened power curve on your shot string graph. (The extent to which regulators have been successful in de-regulating in areas where it is possible for them to do so is discussed in Chapter 7). Dead-head regulators can also cause "creep" which means the fuel pressure tends to slowly increase. 2.4 The following are the results of a sieve analysis. "reg creep is when the regs valve doesn’t seal 100% ie when you fire the gun the reg for argument sake operates let say 80bar. How to prevent creep. 13.
