Powerhouse Performance

Heard mixed reviews about the place but wanted to give it a shot I have a 2014 gmc sierra 5.3 long tube headers high flow cats with built 6l80 and a 2500-2800 high stall and needed it tuned so I opted for the street tube I made an appointment trailered it up there they had it done Same day even after they had a issue with a transmission line that wasn’t seated properly wasn’t there fault at all the tuner fixed it and they never charged me for the fluid or anything and the truck has a night and day difference the staff there are also super knowledgeable and super friendly will be bringing any build of mine there from now on

They are very nice people, listen to every word we spoke about,showed us around and did an outstanding job on my daughter's mustang, highly recommend this group of guys

Horrible customer service, never answers the phone , ignores calls , don’t respond to emails etc If this is how hard it is to get them to call you back so that you can drop your car off I can only imagine how they are once they have your vehicle hostage in hand. This is ridiculous if you don’t want the job just answer the phone and say that Close down at this point

Just left from getting my 2018 GMC Sierra tuned. Very happy with everything! Prior to having it tuned the truck was lagging and shifting hard going from 5th to 6th gear, I’m assuming due to the over sized tires. Shifting issue is now gone. My gas mileage has a very noticeable difference just on my way home from the shop (30 miles radius), speedometer reads accurately now and AFM 4 cylinder mode was deactivated. Overall I am very happy! Just a little upset that I waited so long to get this done. I appreciate those at the shop for getting me in as quick as they did and working around my work schedule, as well as getting my truck back to me after only dropping it off for maybe an hour. 10/10 customer service and workmanship! Thanks again!

These guys did a cam swap,heads,intake,stall,full custom exhaust and installed my lowering springs on my z28!These guys are top notch and highly recommended them for any of your performance needs!
