converter problem? see graph!
I recently hit the dyno with the some changes being made to my combo and overall very happy except for a dip that occurs on the graph. I'm not sure if its related to the torque converter, dyno pick up interference or possibly in the tune.
The combo is basically a stock bottom LS2 with ported heads and a cam. The power is transfered to the rear through a built 4L60 and a Circle D 3200 stall combined with 4.10 gears. The dyno tuning was done with the converter unlocked with zero knock and air fuel at 12.9-13.0.
Does anyone have any ideas what's causing the dip?
