Background:

4.8 bored out to 3.898 with vette rods and pistons. New 5.3/5.7/6.0 crank and Texas Speed 212/218, .600"/.600", 111 LSA, 110 ICL. Pac 1218 springs, rods, etc. TBSS intake and 102mm throttle body. This is in a Rock Buggy with a TH400 transmission with a tight convertor and NP205 transfer case. It had a stock 5.3 before that I swapped the engine in. It has no brake switch, no vss and is tuned as a Manual transmission. Stock 5.3 ran fine until it wore out.

Issue: VE is good, startup is good, etc. But it dies when you abruptly let off the throttle. Without the VSS throttle cracker will never be active. Can this be fixed with throttle follower, some other table Im not familiar with, or do I need to figure out a way to change the cable VSS to electric?
