Power Loss, Turning up Boost Options

[Island_Racer]

Hello,
I am wondering how i see people talking about turning up boost to 17psi on their CT20's yet no one had specified whether they changed spark plug gap nor retarded timing at all......So i turnt up my boost to 17 psi and was looking to see what happens.....sure enough i lost power on hitting my boost mark and saw leaning out on my gauges. Anyone else had this problem?

So i wanna know what plug gap the stock motor 17 psi users have
also how much to draw on the timing...if that will help

Just as a starting point. o, i doubt it is fuel.....at idle my car shows 30 psi and while driving it has maybe 35-37 psi higher than pressure (aka 5psi boost = 40-42 psi fuel....10 psi boost = 45-47 psi fuel)

After servicing the car with new oil and filters the fuel pressure is even higher than before and the gauges are showing a nice rich mixture at full boost....btw, even though my fuel pressure had gone to the right numbers initially, before servicing i noticed that it fell drastically after staying on full throttle, so i assume the rail pressured up but then the dirty filter couldnt maintain good fuel flow....so now after servicing and stuff at 18 psi it even goes into mid 10's, so im gonna put back on my management system to start leaning it out a bit....
