No , keeping boost and egt down is a means of using less torque, the 20psi figure is not the magical number for fuel economy and purely a direct measure of the torque your demanding . Boost needs to be relative to the fuel required for a % Of torque to maintain proper AFR

Well said.

less torque, gearing down early and properly to keep boost lower, and better driving habits = better fuel economy and longer engine life. Limiting boost helps you find the right gear for that hill, helps you keep your foot off the floor too.

My wife says this to everyone -- "Adjusting that nut behind the steering wheel is the hardest one of all to adjust." -- I.E. YOU! lol
