Funktion Performance is awesome! Jeff and his employees are very professional and very eager to help. They went out of their way to help me. I highly recommend dealing with these guys for any of your performance needs. Not to mention the shop is in pristine shape and you can eat off the floor...

Its not often that you that you find a shop (owner driven) that is this professional while being very diverse with services offered. I had my calipers on my Porsche 911 powder coated at Funktion and they went above and beyond while my car was in their possession and kept me in the loop with pictures of the process. Highly recommended.

Great customer service; Jeff notified me ASAP with a problem on my order. Called them up, talked to Jeff, came to a resolution and walked away a happy customer.

I love this shop! I had a boost leak on my F30 3 Series and not only did the fix the issue; they also replaced a coolant leak for me that would have been a bigger problem. Really reasonable pricing and great communication. Will absolutely be going back to these guys.

I purchased the Revo RT330 Turbo Kit from Funktion Performance in Cornelius, North Carolina because they have some of the best customer service and competitive pricing. I had reached out to Jeff Funkhouser (Owner of Funktion Performance) back in April to inquire about the Revo S242 hybrid turbo kit for the Fiesta ST because they were offering it with the turbo core exchange. By the time I was getting ready to pull the trigger in July, the kit had been phased out for the new Revo RT330 bespoke turbo. Jeff ended up reaching out to me at the beginning of this month (after I told him I would need to wait awhile if the core exchange was not available to save additional funds) with a price I could not refuse. I paid for the turbo kit on Tuesday 10/9 and had it in hand on Thursday 10/11. The cold side charge pipe got to me in the same amount of time from the United Kingdom!I cannot recommend Funktion Performance enough. Jeff was super helpful and provided some extremely competitive pricing.

Great experience with Funktion Performance. Had work done on two occasions thus far. Revo stage 1 ecu software then came back for an intake and some powder coating. Jeff is professional and does exceptional work. I won’t take my car anywhere else from now on.

Jeffs attention to detail, professionalism, work ethics, and of course, very competitive pricing, will keep you coming back no matter what you need.

Jeff worked quickly, supplied photos, and was communicative throughout the whole process. If you want someone who is going to take as good, or more likely better care of your equipment than yourself, Funktion Performance can handle it.

Jeff is super helpful and does great work. Would highly recommend to anyone.

Great products at even better prices with the best customer service. Jeff is the man.

Great custormer service, great parts, they always there when needed it.

Excellent powder coating service.
