Great speed shop! The staff were friendly, knowledgeable, and open to working with MegaSquirt. Awesome experience overall—I'll be back with another vehicle soon!

Fantastic performance shop!! Miller mountain went over and above to ensure my truck got tuned properly. I brought my truck in with a trash remote tune and they took the time to dial everything in to perfection. Super friendly service and very easy to deal with. I trust these guys with my vehicles and will be back for all my tuning needs in the future.

Not the People you want working on your vehicle. They will promise you the world until you drop your car off and then they hold your vehicle hostage. Bait and switch the and they are just plain incompetent. From parts not fixed to personal belongings missing from my car. A bunch of jokers.

Nice guys- took my camaro there for a quick tune to turn off the DOD. Didn't take long and enjoyed the car chat afterwards! These guys can make ya go fast or perform some daily driver maintenance, I appreciate a shop that can cater to everyone, not just the super fast guys!

Liars and Terrible Mechanics ! Stay Away From This Shop At Alll Costs ! They have no idea what they are doing , timelines for any kind of work are outrageous compared to any other shop ! Price Changes From Original Estimate to the Day Work is Actually Completed by THOUSANDS OF DOLLARS ! Welds and Pipe Work Are Severly Mediocre/Low Quality . Please BE AWARE and STAY AWAY ! FreedomMotorsportz in EXTON is 100x better .

Nice guys and do clean work. A great local tuner shop that can do a whole lot. Got a stainless steel custom exhaust here and she's minty. Clean welds, straight lines, perfect fitment.

let me start by saying these guys are great! i brought my truck to them after getting screwed by another shop and these guys got on it. with parts issues, and some incorrect installs of parts (on my end) these guys did all they can to help me get this truck finished. theyre communication and professionalism is top notch. now my truck is not done yet cause of a failed turbo charger (on3s fault) and front main seal (definatly my fault on the seal) i’ll will be correcting it and bringing it back as long as i haven’t annoyed them enough lmfao. Art and Logan are 2 great guys that have awesome skill sets and don’t treat you any different because you may not be as knowledgeable when it comes to high performance, but yet they give advise and help further understand everything going on. give them a shot!

My experience was very good with Miller Mountain. I went there for some exhaust modifications for my pickup. Art is a very nice guy and all his crew. They also do state inspection and oil change and more auto work. You won't regret it if you go there.

Was in a tight spot on a road trip with a broken wheel bolt. These guys stopped what they were doing to help me out and get me down the road. Nice honest people. Would recommend to anyone.
