Before I performed the simple boost bypass mod, my dash boost gauge would usually only go to about 8-10 psi at WOT. However after the mod the gauge goes off the scale even at somewhat modest accelerations.

Is this expected behaviour?

 

Boost Bypass DOES NOT! affect your peak boost level. Cold dry weather will make higher boost levels.

 

Cold..... yep, that fits the scenario, thx.

 

You might check into adjusting the bypass. To make shure it letting you get full boost at WOT

 

Hmmmm....... "adjusting the bypass", not sure how.....The bypass mod is kind if non-adjustable, either it's installed or not. Where and what could be adjusted?

 

The bypass isnt adjustable and does not affect boost levels at all.

The only adjustment that can be made is to change at which throttle position the valve in the rear of the blower will close to start producing boost. It is best to just leave that alone.
