surge camshaft

I am 17 years old Programming beginner I have tahoe z71 2011 gen4 227/243, 614/624,113 LSA camshaft .

what reasons cam surge?

Because your cam is huge for an suv and lobe sep is 113

Yeah, holy camshaft size for a big SUV. I hope it's got a 3,600rpm stall converter, otherwise it's going to suck to drive around.

But the surge is because of many factors. Fueling, spark timing, airflow settings.

3600 stall is so high it affects fuel economy and daily use.
your opinion 2500 stall and 3.42 diff ratio are good?
