Default amal valve 'switch' for 2 stage boost

ok, for a quick fix to enable the boost to be turned down, i've put a switch to the amal valve.

its a T34, car normally hold 22/23psi, when switched off it hold 15/16, if that...

am I doing anything wrong here or putting the engine life in jepordy?, or is this ok. I've spoke to a far few people who have done this and say its fine

You are turning it on and off, just like the ecu does.

Its just a switch inside a bleed valve, stupid explanation.

better idea for when the missus drives - put a brick under the accelerator pedal

Depends if the chip file was ever mapped with 15psi at WOT and high revs...

may be rich, may be fine, but worse of all, it may be very lean, on a transitional area ogf the map somewhere between cruise and the top boost line the map was intended to be used with..
