I am personally running the V4 maps from Cobb and power is definitely significant, Car feels completely different. Right now only on Stage 1 with Catless DP and custom rear mufflers. I think there's been some huge power gains with the V4 maps compared to the maps previously released so that might be some of the confusion with small gains on Cobb.
