I asked the shipment to be delivered to Jet Hot they decided to deliver to my home address. It was in writing. There was no misunderstanding. I paid with PayPal and the shipment came to my Billing/Shippinging address. Customer Service did not care or offer a alternative solution. This was my first purchase with Holly Performance and the last, Back to Summit where I belong.

There sniper system is a pile of junk the system is a failure and poor made for the money it is not a easy system to adjust or maintain I have yet to be successful even with a programmer directly connected system floods speractily and can not adjust nor learn fast enough and a large cam is hell on it with vacuum loss I have been trying to make a successful drive with out being stranded for over a year now

Both of my Jeeps batteries died which created an issue reconnecting my Flashcal F5 with my ‘21 Wrangler. Neil helped me figure it all out and was very helpful and knowledgeable. Thanks!

Ordered my flotech headers thru Holley. Spent $800 to have them installed, just to find out there were holes in them from the crappy welds. Took pictures, but can not post them. Very unhappy, $300 for the parts, $800 to install.

Got the diablo tuner/pcm swap can't load tune says vehicle not identified updated 5 times called tech support waited on hold 30 mins to get a person on the phone who has no interest whatsoever in solving the issue just saying whatever to get you off the phone extremely unprofessional

Worst friggin company I’ve ever dealt with! Selling the worst products on the planet. Absolute garbage. Would never buy Mallory products ever again they are trash. And the service sucks big time. Parts never arrived. Had to cancel and chase my money down.

We have been fighting a Holley Sniper 2 for 6 months to get a tune. We have had several professionals look at it and tell us it's internal. Holley tech was worthless and now I'm told I'm SOL. Send it in and pay for it's repairs We tool it off and put an Edelbrock carb on, truck runs great now

Unfortunately, my experience with Holley Performance was extremely negative. I purchased an unlocked car computer at an attractive price, but it turned out to be a trap. The offer seemed good, as they promised to exchange my original computer to avoid additional fees. However, once I sent in my computer, which was in perfect condition, they charged me $647.10 without any prior notice. The problem is that they never informed me about the specific conditions my original computer needed to meet. There was no clear communication regarding what they considered "in good condition," and suddenly, they withdrew money from my bank account without my authorization. This feels like a scam, as they take advantage of the lack of information and customer trust. Overall, Holley Performance seems to focus on misleading people with attractive offers, only to end up charging hidden fees. I would not recommend this company to anyone looking for honest and transparent service. Beware of this!
