The efficiency is impressive, especially if you keep the speed lower than pictured 😉. I saw 21.5 mpg out of it when I stopped for fuel at Quartzite on my way to Long Beach... and that was with over 2,000 lbs loaded in the bed. At first I thought the tank wasn’t filling correctly but nope, it was full... and my math was correct.
The intercooler pipes are just sweet. I only hope I can make mine look half that clean and I will be happy!
