"It was amazing the difference it made. My truck ran so much better and made more power!"

"He is a really nice guy and knows what hes doing."

"Was caught out in the valley with a dead car, called the shop and someone came out and jumped me free of charge. Super helpful and Professional."

"Phil recently hosted the Mopars Unlimited Spokane chapter's monthly meeting and we ran 9 cars across his dyno. Great down to earth guy and will work with your old school hotrod or your new modern muscle!! Thanks Phil!!"

"I called this number and they transferred me to chad, we were talking prices for dyno run, he said 3 runs for 110, the call was dropped or they hung up, I do not know. I was going to talk about scheduling a dyno session when I called again. I tried to call again, they said hello, I said "Is this a company?", I said this because they didn't say their name or what company they were. The person on the phone said you called me, you should know if we are a company. Then they said, why are interrupting my world. I didn't know if I dialed the wrong phone number when they only said hello, because that isn't a way you answer the phone when people are trying to call someone for a service. I indeed called this number not someone's cellphone. Performance & Dyno needs to answer the phone saying who they are."
