I doubt that.
You can only ask so much of the F650 GS. If you spend the equivalent amount on rider training and practice, you won't need any FI tuning.
No..... I'd say 2 with stock exhaust..... and that might be optimistic. But control through out the entire rpm band, should be the reason you would do this. Not for the power. Both of the twins are way beyond lean...... Mapped to satisfy the EPA. That is where the real benefit shows..... Control. On the other hand, if you header, and pipe it, you need the PC-5, as you are running crazy'er lean. As mentioned earlier, HTCA has a great product, and I would have settled for that, if I did not want a bit more, in the shape of Header, and pipe.
