I have been at their mercy for 2 years. The engine rebuild has taken over 18 months. Promise after promise have been broken. I feel like my life for the last two years has been waiting for a call back. Currently I have spent over 8k and I cant get a call back. Lastly they blocked me of Facebook completely removing one avenue of contact. Pretty sure this will end with a lawsuit.

I got a bunch of work done on my N/A setup. Diff gears, drag bags, dyno tune, and clutch install. Most of the work done was satisfactory but the morning after all of the clutch fluid had leaked out due to a loose clutch line. Lethal did right by covering the tow back to the shop and fixing the line but the tune was terrible. The car made less power than it did before and ran really rich. Not a fan of dealing with Shaun at all. He bad mouthed my previous tuner and said he uses too much timing. I also had a friend bring in his LT1 Formula and they had no interest in working on it. They said just put an LS in it. Cant say Id recommend this place to anyone but some people do have really good luck here. Unfortunately for me it was more bad than good.

Danny and his crew are the only guys that I’ll allow to work on my Z/28. The upgrades he has done are beyond my expectations.

They fixed my sons Camaro and timely manner. Would take our vehicles back.

They did use mats on the fenders so that’s kinda ehh, but they did clean off the finders when I got there. Owner nice and responds quick

First of all let me state Danny and His guys are the nicest bunch of guys. But I’m very disappointed in the way this 40k plus turned out with the fit and finish on this LS9 swap. Headers touching frame, air Conditioner compressor touching frame and motor dies at stop light with AC on and now starting to pops fuses. There has been many other issues along the way including catching my insulation on fire which could have been a total loss from not disconnecting battery after before fuel injector upgrades. After calling and trying to bring my truck back and trying to work with Danny and still not getting issues resolved with no call back and ignoring of text I’m starting to get the message loud and clear. I’ll leave my review and find another shop to fix the issues. Reviews are supposed to be based on personal interaction, quality of service and finished tangible product. Now Im faced with additional cost of having to pull motor and redo motor mounts and other fine tuning details that should have been done while this truck was in Danny’s possession for 5 months. I really wanted this review to be a 5 star review as I am a big believer in leaving positive feed back for businesses. Unfortunately I have given Lethal Performace every chance to make it right with me.

They are great and really know what they are doing. Their pricing is really fair and the owner is easy to work with.

What I originally thought to be a nice place and great customer service...was changed. My first and only purchase so far was a bottle of oil. Super simple purchase. After I returned home and was prepping my truck to use it, I discovered I bought a pre opened and potentially used bottle of supercharger oil. When you spend 1000s on a supercharger, that last thing you want to skimp on is the quality of oil. I find this shady business as it was on quote his last bottle of oil sold at retail.

Just asked to get a tune and instead of helping me out two guys came out the shop talked smack about my car in front of me then said nah it’s not possible but didn’t even try to fix the problem or tell me what was wrong with it .

Guys Ive owned many vetted in my lifetime......I took a buildt c6 to lethal that needed complete drivetrain from flywheel back....I mean the whole train.Yank converter, brand new torque tube, new trans pump, etc.Danny and John didnt beat around the bush. They are very knowledgeable and straight forward.In my opinion...thatsthe only way to be......they got my Vette going and I couldnt be happier with the cost.Danny and John

My first time dropping my c6z of at a shop so many people told me about the legendary tuning and great work lethal does I’m more than happy with my new build in my c6z will be pushing more power but on top of that had 0 issues with the company customer service is great and so are the employees I highly suggest lethal performance of Texas for your next build !

Thank you, Lethal Performance of Texas for taking on my 1976 Lincoln, Continental Mark IV repair It is very nice when companies value military service and help our Veterans.

Awesome work Danny and company!!! You made my C7 fun to drive again. I knew I was in the right spot when I saw how clean your shop was. I’ll definitely be back for more go fast parts!

I was very impressed with the organization of the shop, it was not only clean, but neat & organized. Their customer service was excellent, and the Tech that took care of my Camaro SS 1LE, took time & pride in his workmanship, when installing my Borla Atak exhaust system.After thanking the Tech, his reply was, “This is what I love to do.” I would would definitely recommend this shop! — Robert
