No driveability issues with carb at all. This CSU carb is awesome.
It has boost referenced power valves which bring the extra fuel in with boost.
My datalogs from a pass show the A/F starting at 11.4 at the launch, and creeping slightly to 11.8 at finish line. I actaully blame my water/meth kit for that, as it operates on a hobs switch and flow is constant.

i have a 69 camaro i flipped the drivers side up and forward and the pass side is down and forward. hey 3 pedals im interested in your carb setup i bought a csu after fighting my homebrewd 800. anyway i had a lean transition problem and what finally fixed it was opening the secondarys 1:1 with the primaries. it had a lean transition so bad it back fired threw the carb and i ended up bending a rod. with the old carb and the csu until tried the 1:1 then it ran mint. but i only have one csu brpv . kevin set the carb up with a standard pv in the front and brpv in the rear but the boost holds a standard pv closed. main reason i bought the csu. just curious if your runnning two brpv or not i have a ly6(6.0 with l92 heads 9.5:1) with a 215 230 ls7 cam. 750 csu carb. intercooled no meth. and a older garrett t6 flanged tv7511 turbo with a 80mm compressor wheel.

my CSU has a regular PV in the primarys, and a boost referenced PV in the secondarys. It was a bit lean on tip in as well, but some larger squirters fixed it for me. I have a wideband to help tune, so I could see that it went lean with throttle movement, and then recovered with steady throttle, indicating the shooter size was where I should make a change.
