Hello,

I'm looking for some help in dialing in a cammed LS3. The car runs and drives well. Trims look great. Plenty of power, dyno'd strong, 450hp. It's always had a light load/cruise surge. It's felt under 2500 RPMs at light acceleration and cruise, as if the car is moving back and forth with steady throttle application. It's minor, but it is there, some less sensitive people might not feel it.

The build is the following:
Corvette LS3
Stock Heads
G6X3 cam (big street cam)
1 7/8" long tube headers and high flow cats

I've attached the tune and a log if someone could take a look at it and offer some pointers. Thank you!
