Two questions for the MC-1 experts:
1- To much boost I am running the stock WG spring and I am getting 12-15
LBS of boost? I thought the stock was 6 lbs? I checked the WG diaphragm and
didn't see any holes (I know that doesn't necessarily mean much). Any ideas
why I am getting this much boost. Oh - stock ECU also
2- Air - Fuel mixture. I just installed a JC Whitney air-fuel mixture
gauge. At idle or when I lift off the gas I get slightly rich reading.
Under boost I get a lean reading. Is this correct? I thought I wanted a
rich reading under boost but then I am don't completely understanding all of
what happens on the CIS system.
Any ideas are helpful. I want to get this straightened out before my next
86 4KTQ rally car
