since the motor swap to the 6.0 I've have an exhaust leak my truck has gotten 4mpg on average. I mainly drive around town.

changed the broken headers back to the stock manifold stopping the leak. it improved my mileage almost doubling it!

I got a tuned ECM that is more aggressive. I'm curious to see what this will do. I'll be installing it possibly tomorrow!

stay tuned
