A boost relief valve releases boost above approximately 22 psi before it reaches the MAP sensor so the PCM does not see overboost and defuel.
An overbosst fooler does not release boost but limits what will pass to the MAP to approximately 22 PSI to prevent defueling.
They each have there downside. A relief valve lowers boost. It essentially becomes a small boost leak when it opens.
An adjustable fooler can go out of adjustment and allow to much boost to get to the MAP and causes defueling.
I have an adjustable fooler which needs ocasional adjustment. I have ordered the OCR referred to by Mike (Big Poppa) to replace it.
My 2¢.

Maybe Im confused then. I thought I needed the relief/fooler to keep the fuel from tripping out. So how would I "tune" anything ?

Tuning would involve after market tuners such as DP, PHP, Tony Wildman or TS Performance. They can program tunes so the PCM will not defuel due to overboost.
