Dawes device tweaking.
Could anyone help me with a Dawes device I have fitted to my car? I want to turn the boost down but don't want to touch anything in case I **** it all up.
Ideally someone near to me and I'll pop over to you and sort out a 'drink' for whoever can do it. Ta.

Put a dab of typex or similar on the top and bottom section to act as a guide to how much you turn it.
Slacken the lock ring or nut.
Unscrew ie anti clockwise for one full revolution.
Tighten lock ring.
Warm up and road test. I assume you have a boost guage. Running a Dawes/GBE without a boost guage is a bad thing and thoroughly NOT recommended.
If the boost is still too high take out another turn or half a turn until you get it where you want it.
It's a doddle.

With no boost guage, or one fitted temporarily to effect the fit, you are asking for trouble.
Before fitting a Dawes/GBE/one of the alternatives, you need to know what boost you are running, what boost you are setting to and I always then check the AFRs and listen for DET.
If that proceedure is not followed and you have no boost guage you are courting disaster.
