They are vendors to both. It would not be a good business decision to mix them in the same message.@LethalPerformance any chance you could post a dyno graph with your whipple tune and JB4 Map 3 overlaid on each other. They made just about the same power, but I want to see differences in the curve.
What I can tell you is I just installed the Whipple. Prior to that, I was running the JB4 on map 3. The Whipple is hands down better and feels faster than the JB4 on map 3.
