C3, your idea makes sense, and sounds reasonable.
The problem with your idea, or the flaw in it, is this.
Your idea assumes the kit you buy, and the flash Ivan does is the same thing, and its not.
Ivan has access to at least 75% more of the ecu than the kit will ever dream of offering.
So, its not an equal comparison. If a person is dragracing, and all they care about is top end power, then the kit will do a great job.
If you are street riding, and are concerned about small throttle openings,and how the bike feels, thats where Ivan holds a massive advantage.
