It is of paramount importance that the tune you fit matches how and where you ride.
If you spend all your time trundling than a tune for thrashing may well bring no benefit.
The first thing to do is ANALYSE. You maybe able to do something easy with TuneECU and a 20 dollar cable. Most of us (at a guess) spend most of the time at 20% throttle or less.
Merely modifying the F<->L switch values will make a difference. At 35% I am very deep into "bye bye licence" territory. At 50% - it's getting close to custodial.
If not then the best thing you can do is find a professional tuner and explain what you want. After that well you can potentially go for something like a Dobeck or PowerCommander.
If you REALLY like to see everything down to the last detail - then I'd go for a PCV with AT. But please - if you fit a PCV/AT use the map/gear feature.
Not a tune. not a tuner. It is an add on piggyback device that intercepts the signal to you fuel injectors and makes that signal better which improves performance and increases MPG.
