No my cobra is not but my truck is.
First thought I had was the tune is off. The L guys get this if they change something and the chip is off. I don't think its as much the chip type as the tune thats on it. I would say find a new place to dyno tune it for you and see how they do. Ask around your local area to see who is putting out some good stuff right now. The timing may be off or could be something else.
