Hellhorse Performance 18083 Farm to Market Road 1314, Conroe, TX 77302

"Ordered the Sync 2 to Sync 3 upgrade kit from Sam. Customer service is top notch here—don’t bother looking elsewhere. Had a few issues with the equipment and Sam responded immediately and has taken care of everything! Highly recommend—great price, excellent service!"

"Jeff and his team did an amazing job getting my car back on the road when I got it back. Maintenance had not been done in some time and they put it back on the road running better than ever! Performance upgrade next!"

"Stay away! This place is the single most unreliable shop, after trying to reach them for 2 months. The customer service rep says he’s going to relay the message and have a tech reach out and it never happens, it is always a lie, they never call back or help you with any issues. They built my car and after a week my car is not running right and they don’t answer their phones."

"Waited for almost 2 months for a wrap to come was told multiple times they were reaching out to their distributor multiple times reach through email got no response was only able to get a hold of Sam when I’ve called in requested that I wanted a refund and was told they were going to reach back out to the distributor. I insisted again I wanted a refund and had to wait an additional three more days before calling back in and talking to Sam again and saying issue my refund before he said OK. Very disappointed."

"Highly recommend the guys at Hell Horse! These guys stayed late on a Friday night to get my car done & have it back to me. Now that is fantastic customer service. Thank you! They were honest throughout every step of the process. They gave me the best & most upfront quotes when it came to exactly what I was looking for. No up-charges, no surprise jumps in price between what was mentioned and what was done. They are friendly, personable & know exactly what they are doing when it comes to performance mods. The quality of work speaks for itself; they did an amazing job & I will definitely be making the drive out for any future work on my Mustang."
