    LT4 Supercharged Crate Engine Surge

    Working ona 69 Camaro with a LT4 supercharged engine in a 69 Camaro. Dynos well makes really good power but on the road it surges at WOT. It does well up to 3/4 throttle but above that its like it has traction control. I have attached a log and tune. I notice the hp fuel fluctuates at wot. What am I missing?Layman surge.hplLaymon PROG.hpt

    Log and see if any Tq management advance is being pulled when it happens?

    Also look at ETC tq mangement, will say chassis (if traction control), should stay on axle through the pull
