CTS-V Driveability
Hello,
I recently bought a modded 2011 CTS-V. It seems to be having some driveability issues between 2-3krpm. If I accelerate through this rev range at 50% throttle it will stumble. Typically it is worst at about 2500rpm and will sometimes stumble pretty hard before continuing to pull. Above 3krpm it seems fine. I cleaned the MAF sensor and visually inspected vacuum lines for leaks but it did not help. It is not throwing any codes or CEL.
Mods are cam, exhaust, CAI, ZL1 lid, pulleys, injectors, plugs, intercooler.
Any thoughts what might cause this issue?
