If an ERST has 2 stage boost and it is put in the lower boost range and goes into full throttle would this cause serious over-fuelling?

i doubt it would 'seriously' overfuel... it would obviously overfuel somewhat though. (assuming the fueling had been set up correctly in the first place! )

It must be quite a difference between the fueling from 18psi to 10psi on a good strong actuator?? Just wondering if its going to cause problems if I fit 2 stage boost to my car?

i never had problems when it was fitted to my car.. the thing is it depends how the fuel has been modified (if at all to cope with the 18Psi)
the normal Ke-jet fueling cannot (automatically) adjust to cope with boost pressures over 10psi (approx)
when you have the ke modified then the car WILL over fuel on idle and part throttle anyway... it wont do much harm in fact it will prob help to keep temps down. Unless its VERY heavily overfueling you will be fine...
IMO you would be best sticking CO meter up the exhaust and drive down the road if its 10 or something you have a problem!

Are u talking bout a normal switch that shorts the amal valve , if u are my car has i and think its only 4 psi the difference between high/low mines is 12psi then 15-16ish
