Nice work Bill. Love to hear about other folks getting their Skoolie into drag racing shape. We're huge fans. The gas mileage gain and performance has been a godsend on our rig. Looking forward to the improvements you keep making. I'll keep you updated on the results as I get more time with the system.
Keep crushin it! ![]() ![]() |
