I have not done this specific upgrade, but the question I have for you is, what is your end goal?
No, I would NOT recommend you get that tune, you have done none of the upgrades to the motor to take advantage of the EV Stage 2 tune. This is for a non-stock motor and bare minimum upgrades I would suggest with this kind of tune is replacing the stock charge tube and a clutch kit.
- With increase in power you need to be able to control and deliver that power to the ground, ie clutch kit.
- The stage 2 tune will increase your boost. The stock plastic tube already has issues with the 14psi that is stock, pushing 19psi youre going to find yourself on the side of the trail!
The upgrades you have now do nothing performance wise. The S&B increases filter longevity (no performance gain), and the BOV fixes a leak issue that stock has.
If you want to reflash your ECU for increased efficiency with a
STOCK motor, I would suggest Bikeman Performance they have a tune just for this.
