Doug, Just got back from vacation today,....sorry for the delay. Now you are seeing the problem with jetting a stock cv carb. The jet needle well spacer is too small to flow enough fuel for max boost. The needle is wrong too. Install a slide stop and you will see what i mean. If you get the main jet size correct for best response it will be too lean on top and a bigger main won't help because of the needle jet spacer. Send me a stock needle and I will do the mod that worked for me. Send me your last dyno test too, along with boost specs. Jeff Churchill J.C.
