"Travis at powerhouse diesel was a pleasure to work with. Hands down best customer service I've experienced. Got a full fuel race tune for my 6.0. No turbo lag smooth strong power through all gears no hard shifts. All around great product from a great company. Look forward to doing business with them again. Highly recommended."

"When my 6.0 diesel had unexpectedly died on me I got it towed to powerhouse immediately. I talked with Brad and got the issue fixed within two days! They were also able to get some small needed maintenance done. They were awesome to work with and will definitely have my business for any future diesel in-devours!"

"From gaskets and a new 9 blade to a fresh set of wheels and tires. These guys, especially my man Brad Lilly, will go above and beyond. Highly recommend for minor fixes and major upgrades."
