Here is the tune file, tuned by Kesatie Motorsports back in 2014. This is a 2005 LS6 CTS-V with a 228/228 with 114+2 LSA custom ground cam, ported LS6 throttle body, and Kooks longtube headers. The car doesn't currently have a wideband. The setup made 403/369 when tuned.
The issue I am having is that when the car is coming to a stop and I throw the car in neutral, the car will drop idle to around 500rpm, surge, and then catch itself and even back out when stopped. Additionally when I am coming around a curve near my house, with the car in third and keeping the clutch in until the corner exit, the car will drop the RPM and stall out. Should I be looking at the base airflow table or the throttle cracker/follower settings? Not new to HP tuners but the Gen 3 platform is a first for me. I appreciate any and all input/direction! The car drives great otherwise and pulls nice and hard.
