I would appreciate any ideas on why my car seems to be pulling timing in second gear when the knock sensor is not seeing any knock. This is an 09 CTS-V at an 1/8 mile track.

gonna need the tune to know exactly what timing it should be running.

It seems like the timing gets erratic whenever the mass air flow sensor hits 655.35. I am not sure why this is happening.

Take Care,

Try putting B2510 back to stock. This has proven to produce some odd results when it is not stock. And it is simply a TCS commanded max torque number, so it simply sets the max torque number that TCS can command during TCS intervention.

What are you working toward achieving? Keeping TCS off?
