Premium gas and the power difference is right on the graph. Picked up 20rwhp & 17rwtq and the tune was $250. With the added mileage I'm now getting, this should make up for the increased cost going to premium.
If you figure my car is putting out the rated 361hp & 385tq, then the driveline losses are about 18-19%. Looks like I'm around 385hp & 410tq @ the crank.
