How much boost does 5 star 93 performance tune make?

I've seen spikes of 20 psi with my 5star 88 perf/tow tune. It will hold 18 psi for several seconds. I monitor mine with a Bully Dog watchdog monitor. You can really hear the BOVs working when boost goes over 16 psi.

I'd be interested on where you found the FX gauge. I have the LED Roush gauge. The FX would have been icing on the cake! Does yours go completely black when the truck is off??
PS...whats the OFF/ON switch where the 4x4 switch normally is? Is this an FX2 feature???
