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)

i am running .28 gap IIRC, still using stock heat range plugs. what kind of fuel do you use? that will play a big role, also alot of the guys here run water injection, which REALLY helps.
