Question for you folks .... We're NA and probably going to stay that way - alpha CAI, JRIs, Bassani exhaust, upgraded swaybar and links, bigger tires ...... what would be the pros and cons from doing Bob's tune?
The tune will help - but I have seen plenty of Slings with your upgrades and the stock tune with no issues!
If you are happy with the performance let it be.... Take it from a junkie the pursuit of HP is as addictive as any drug.
