First rate service and backup! Shelley and Brian were really helpfulFive star service!!

Excellent products and customer services. Product performed exactly as stated on website.Bought a dyno boost device, a 02 simulator and performance spark plugs to install on an 2015 Articat snowmobile.The dyno boost device provides noticable HP and better fuel efficiency. Also and advantage is that the engines fuel/air mix ratio can be fine tuned for different operating temperature providing the best achievable engine performance. Tested at -40 deg C with over 4000 km without any issue. The dyno boost is also equipped with an 02 boost switch but found out that it triggered an ECU alarm. Therefore I added the 02 simulator device which took care of the alarm and even gave a better fuel efficiency. With both devices the engine uses 20% less fuel than the stock engine while achieving more HP (tested many times with high tech tools).The performance spark plugs provided an improvement on cold starts (-20 to -40 C) and better throttle response, although one spark plug fouled after 100km of running time but I will try another set as it occasionally happens to foul spark plugs on these engines.All item purchased came with an installation guide and were pretty easy to install.Shipping was extremely fast and customer service is just awesome!!!Totally recommend buying!

The worst of the worst. Please be ware. One star so I can prevent you getting ripped of. Worst.

This was my first order with Magnum Tuning, but it wont be my last. The simulators I order were exactly what I needed and my truck is back to running great with NO check engine light. I want to give a special tip of the cap to Kevin for his help and advise. Great parts, good service, and even received them early with no shipping cost. Thank you very much, Chuck

Great experience, got my parts delivered to Australia in time at all. The parts supplied were the correct fit, had no dramas at all with product and was well priced too. As a new customer, I was very happy with service MAGNUM tuning provided. Very prompt in replying, great communication and always friendly over the phone.Thank you all to all involved.Robert N.NSW (AUSTRALIA)

The shopping experience was great and the product works as described. Price was a bit higher but the 10-year warranty was a deal maker. My item arrived very quickly and well wrapped. Customer service associates were very helpful and efficient.

Do not trust their website for part compatibility. They will try to scam you out of shipping money to send the falsely advertised parts back. Its clearly some foreigner that doesnt understand US business law and is running this company like its in some third world country. Check out their BBB profile, theres lots of people that have been scammed by this shop.

Dont buy from here they send you broken items then scam you and make you pay to ship it back i was harassed they sent emails evil emails just because i ask for a refund ... IF you check on BBB THEY HAVE BAD REVIEWS THIS PLACE IS A FAKE STORE DONT BUY FROM HERE THEY BUILD THE ITEM AND MAKE IT LOOK LIKE WHAT U ORDER BEWARE

Delivery was much faster than expected and the quality of my product was top notch. Exact fit without modifications. Short instructions but emails helped. Product works as described. Good value for price.

I own a 71 Norton Commando and last summer I had a new electrical harness, gel cell battery and new Amal carburetors installed to give me peaceof mind on the road. The bike started on one kick but still needed me to keep the idle by twisting the throttle until it was warmed up, but after I installed the Brisk premium #3175 it idles on its own and accelerates like never before. As a matter of fact as soon as I got back from the first ride I ordered a pair for my 1962 BSA A65. They may seem pricey but they totally complement all the time and money I had already invested to make the bike reliable.

Everything went through smoothly. We spoke to a representative about our performance needs. He guided us in putting our order together very efficiently. We will keep ordering.

Awesome and thorough service, fast shipping, matched with affordable prices and excellent technical support. Techs were more than willing to guide me through the hook-up of my dyno tuner. Special thanks for free shipping and the free gift. I highly recommend using magnumtuning when it comes to performance upgrades.

Easy checkout, my plugs arrived on time as promised, even a little earlier. The reps were courteous and will continue order from magnumtuning.

Awesome experience ordering and even getting warranty on an item. I highly recommend this site

Dealing with magnum tuning was a very easy process and I definitely see myself doing business with them in the future .

Great product, easy to hook up. Works great haven’t had a problem.

The O 2 simulator for my truck was easy to install and works great i had support from the company on the WEEKEND even at 6 pm on Saturday and Sunday morning magnum tuning you area great company i would recommend them to everyone great product at a great price and fantastic support. thanks

I purchased dyna chip for my avalanche, and got it sooner than expected with free shipping! Installation was a breeze, had no problems. I already noticed more power and throttle response and seen 2 more on MPG, im still working with it and trying to fine tune it. I purchased the tuner strictly for performance gains and it definitely made a difference. i can tell that my truck runs a lot better and is a lot more responsive than before. Im very happy with it. The price was fair my only criticism is that they dont have a call center but when i contacted them via email, techs were more than willing to work with me. I will definitely recommend these guys to others

PROMPT customer service would be helpful
