Still Amazed at your skills, The Demon is the scariest thing I have ever driven, and with the upgrade supercharger and intercooler we decided to go with it is now a heart attack on launch and adrenaline rush for days after 1 run hands are still shaking, didnt think it was possible to get anymore from her but your Tune and abilities are phenomenal. 10 stars great work, professional, and the only person touching the DEMON..

Brought my BMW to Chris 10/25/18 and had to self repo it today being 3/21/19 The paint on the car was ruined Interior was in pieces, Lost the $260 key for it, Removed emblems and never put back on. Lied all the time and said it was done over 4 times followed by a lie that something else was wrong with it . Poor service and all the good reviews are from his friends which at the time included David Bryan another person in the Lewiston area known to rip people off. Money was not a issue it was a poor person CHRIS DAVIS ......

Bought a suburu legacy 2.2l . Spark plugs were burnt suspension shot witha check wmgine light . Chris at davis performance fixed everything very reliably and proffessional

Amazing service, affordable pricing on parts and labor, the owner is amazing at what he does I will only be using davis performance tuning for my auto 🚘 needs

Ive seen pictures of their work and it is no where near professional quality. Messed up a friends vehicle pretty badly over it.

Chris is very professional and does excellent work.
