I'm stranded just East of San Antonio on my way back to Phoenix. Turbo (I believe) is making a loud wooshing noise at high boost, mileage has plummeted and Power seems reduced. Can someone recommend a good tech?

 

Try this, it's near 1518/ Interstate 10

All Out Diesel Performance, The Best Diesel Service Antwhere!

 

Thanks for the recommendation. I took the truck to All Out Diesel this morning. Found the plastic boost hose on top was cracked. Replaced it with an aluminum one off an 05 F450. Total cost was $150.

On the way to the shop, my MPG was 11.2
On the way back, my MPG was 16.5

Big difference...
