Sbc-ID Problems

Here's what I have:

Downpipe 2 1/2"
Scoobysport Exhaust
Intake (don't like)
GFB BOV
S-AFC
SBC-ID boost controller & Power Meter

I just got the boost controller and I'm having problems with it. I have the boost limiter set at 17 and boost ratio set at 60. Gain is set to 5. When I get on the throttle to take off I get right at about 16lbs. Then it starts flucuating from about 18 down to about 14. This sucks! I do also get about 16 lbs with ~15% throttle which = very lean. What could be the problem? I checked all the hoses and they seem to be air tight. The instructions don't really cover the settings too well, so I don't know which one to adjust. Anyone have any idea's? Help me out here!!

turn the ratio down to 50. if you want the boost somewhere @ 16lbs. (@100 ~ 32lbs, then @50 ~16lbs). hope it helps!

So far the boost spiking hasn't been a problem. Now if there was just a way to keep from part-throttle full boost. Anyone have any ideas if I could fix this using the Safc?

I've done a lot of experimenting w/ mine and I find that ratio set at 52 and gain set at 50 works best. It seems a little high, but it runs perfect for SCCA racing and I don't get detonation on the street. Mind you, I do not have any upgraded fuel system or chip. Just piping and pulley.
