PowerFab is hands down the best performance shop in Houston. I bought my 2018 Jeep Trackhawk in June 2020 and the dealer detuned it. It was not performing the way it should, I was able to find out who the previous owner used to have it tuned in Houston. They tuned it but it still wasn’t running right. I took it back once more and it still kept dying on me. They wouldn’t return my calls, so I decided to try PowerFab. (A buddy recommended them to me.) Scott is very knowledgeable, direct and honest. They got my Hawk working well beyond my expectations. The only place I will go to and I highly recommend.

Ive driven past Powerfab almost every day since they opened up on Louetta, I reached out to them after i tried to install something without the proper tools or experience.They squeezed me in and got my car all fixed up. the price was very fair too! I will definitely be using them again. Scott communicated well and they were able to fix my car way ahead of the originally scheduled date.

Powerfab is hands down my favorite performance shop in Houston. I have an SRT 392 that is being taken to another level by these guys. I am VERY picky about people working on my car. I spent about a month researching and visiting different performance shops in Houston before deciding to go with Powerfab and will only be going here in the future. They are incredibly welcoming from the second you walking in the door and very knowledgeable about what they do. Scott has helped from the beginning to figure out what I want out of my car and is always willing to take the time and explain how it all works. I have had a few minor modifications and a tune so far and plan to twin turbo. If your looking to get more out of your car you will not be disappointed visiting these guys.

As others have posted good and bad reviews I’m going to say be careful what you ask them to do and what your asking them to work on. Paid them to tune a z32 and rewire a Haltech. They did neither. Claimed they couldn’t tune because of blow by. So took there car to actual great performance shop and the tuned the car and made over 800HP with no problems.

They modified my Chevy SS. I am very pleased. I got to 170 mph and it had plenty more to go. Unfortunately I ran out of road.

My 2013 Corvette 427 spent 2 months at Corvettes of Houston with a hot start issue. They never could correct it. Powerfab took care of the issue in an afternoon. They’ve done a couple jobs since as well. They’re my go-to moving forward.

Always willing to answer questions about street/race cars. Thanks Powerfab!

This place is 5 stars all around. Used them several times to have my car dyno’d and tuned and have received by far second to none customer service from Scott and his team. Highly recommend this shop.

Excellent team of very knowledgeable experts.

Super disappointed with my visit after all of the good things I heard about them. I dropped off my HCI Trans Am there for a simple tune and when I left work to go pick it up I got in it to start it, and revved it a little while still in park and immediately died, I thought maybe it’s cuz it’s not all the way warm, well I repeated the process about 6 times and died every single time. I go back in and explain to the front desk what it’s doing and the guy gets a attitude with me as if I don’t know what I’m talking about, them he tells me the tuner can’t do nothing about it tonight and I’ll have to leave it there overnight and pick it up the next day.

Jeremy and crew are simply the best around.I can honestly say their is nothing around like PowerFabs. Not on this scale.A+ service, and they are willing to let you take baby steps into a large purchase/work being done.

Scott is very knowledgeable! Dude knows his stuff. My Hellcat is running like a beast !

Always a great car experience! Thanks Jeremy!!

Adds more power!!!

This place is great! Owners and tecs are knowledgeable and friendly. Was looking for a shop that could handle a classic car with modern upgrades and they passed with flying colors. From what I have seen they can do everything from simple power upgrades to wild race cars.

Awesome shop. Took my car in to check tune ended up having some issues. They got me fixed up and back on road same day. Took the time to talk to me about my issues and future plans with the car. I would recommend to give them a call for work.

Great place to get some performance work done. Very knowledgeable and does awesome work. Jeremy was very helpful and gave me good advice on the direction for my car.

I Was recommended to them by a friend. Worked with Jeremy and thought he was really knowledgeable and did a great job on my car. Im very satisfied with the work done and would recommend them.Josh J.

Bought a used Camaro SS from a dealer that had quite a few MOD’s. The tune was horrible when I bought it but these guys came in put a hell of a tune on it. I highly recommend these guys if you want a spot on tune.

Seems to be a well put together team with a common goal. No tuning nightmares or complaints here. Truck runs good

The best. No doubt. Better than the rest :)

I had my Trans Am Dyno tuned at Practice. It was unreal watching my car roar through the rpm rang on the Dyno. When it was done my TA drove great and I had a very proper Dyno graph printed on top notch paper ready to be framed. A+

The guys were very informative and got my 350z fixed pretty quick! Going back when i get some performance parts for them to install!

Very impressed, very clean for a big shop, nice, friendly, organized, pretty much full service and performance minded.

Had them instal a cam kit I bought (wish I would have just got all the stuff at their shop) and torque converter for my 2015 chevy 1500 prerunner. They installed it all great and tuned it. Whole different beast of a truck. Their turnaround time was great considering I just dropped in unannounced with the truck and parts.Will be bringing the truck back for forced induction of sorts later.

Awesome place for Performance installs. Did an awesome job to awaken the beast.

Tuned my cammed C6 vette, could not be happier car runs awesome and they are great to deal with

Methanol can be hard to find in the Spring Cypress area. They have it. Friendly staff and good service, too.

These guys did a great job installing a downpipe on my Volvo. Jeremy and his team do it right and have a new customer in me.

They provide top notch customer service. Going to them for years for modifications.

BEWARE AND PLEASE READ ALL OF THIS ! Put like this -> brought my car to them with bad lifters, pushrods, and cam lobe. They proposed a cam package and didnt give me any options of what I can get and took things in there own hands and got what they thoughts was best. 45 days After the supposedly 6-7 day install they I call and Jermy tells me that I now I have a busted transmission since they couldnt get the tune right !!!!! Needles to say Im pretty pissed that they wouldnt own up to burning it out on the dyno trying to push it into gear. John on the other hand was somewhat understanding. So another 3500 later on a rebuilt transmission and tune from my new guy Im running along with a baby CAM. Power FAB DOESENT KNOW SQUAT about HEMI MOTORS BEWARE!!!

They are very bad they waste your time and they say they can do something and tell me thay can’t do it onemce I get there

Very friendly helpful staff

Awesome builds from this place they are the go to people for speed

Knowledgeable, helpful, courteous, and efficient .

Great service
