Took my rc390 down to be dynotuned yesterday. My bike is pretty much stock. K&N filter with the lid off. It ended up with 41.5hp and a really nice curve. I rode it about 120 miles this morning and couldn't be happier.
Significant difference in the mid range!
The biggest thing I noticed was my fuel mileage. 111 miles and I burned 1.8 gallons. That's 61.6 mpg! I was really impressed with that.
