Great customer service

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full

I called in to get advice about my 2024 Road Glide. I talked to Chris about which would be the best cam that fits my bike to match with the Thunder.

He gave me great advice and a good suggestion. I would recommend talking to Chris.

His customer service was awesome, friendly, and wise. Thank you, and I'll be seeing you soon to be upgrading my Road Glide.

Tuner questions

I am getting a weird hesitation on my throttle position when I try and hold a steady speed with my bike. I cant tell if this is a transmission issue or turner issue and I live in Arizona and am looking for a shop that Thundermax tunes. I think I have found one in Cavecreek and am taking the bike there in two weeks

Can't get my computer to update to new firmware

Updated by user Jul 29, 2025

Not really know what to say just can't get my ECM where it needs to be. Not sure what the problem is still has a 4000 code BCM everything else is working

Original review Jul 14, 2025

Answer the phone and let me talk to someone. The code on my BCM is 4000.

The code on my ECM is 00252001. This is a 2025 CVOST with your model number 309604. I bought it from A1 Cycles, and it says last time updated last September of 24.

I can't get my computer to get the latest firmware from you guys to try to update this thing and get my problems fixed. Help me.

FedEx tracking showed delivery was "canceled by shipper" then magically the package arrived.

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full

Get a different shipper. FedEx is engaged in retaliatory behavior because I gave them a 2 star review because I was at home waiting for the expensive package to be delivered and they still left it on the porch and did not even so much as knock on the door. Or at least require a signature at delivery.

Help with tech questions

being able to speak with a live tech instead of emails would greatly improve your company...as much as these cost , you would think that some accessible tech support could be made available

Terrible customer support

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full

I called thundermax about an issue with there ecm for a harley motorcycle. They have no one to talk too, everything is done by email.

With cost of their product you would think they would have someone to talk too. I will never buy their product, they'rer other products on the market that have 100 percent better customer support.
