OK, it's been a few months since I installed a 12 O'Clock Labs speedo healer. Used my GPS to calibrate. About ~9%. What I've noticed is that the healer has hurt my fuel mileage, by about 9-10%. So here is the fix I'm using for the VTR's poor fuel economy. I just adjust the settings on the healer and I get much better economy. It's great. I just set it for what ever mpg I want to get.
Oh yeah, I also have some ocean front property in Lake Havasu City, AZ that is for sale, and it includes the Londen Bridge.

 

You should dial-in a few more ponies and ft-lbs while you're at it. I feel stupid telling you this. I'm sure you've already thought of it.

 

Ah, modern technology! Back in the day, the best we could do was add more fuel to the tank. lol
