In my experience, and I've had both products on cars in the past. The car just runs smoother and better with a flash tune. There's also the fact that it makes more power with a flash tune. My opinion is that having the computer that was designed for the car do all the work is better then using an external controller. Again thats my opinion though. I dont think you will be disappointed with the extra power from either one.
