Redshift 468 and Thundermax
Have any of you put in a similar bolt-in cam with a Thunder Max ? Mine is a 2020 Sport Glide with a 107 and 34.400 trouble-free miles.
I'm curious as to how happy you are with the Thunder Max and cam. Any electrical issues or odd motor noises ?? Are you happy with the performance gains, if any?? Would appreciate any info you could give me on a cam and Thunder Max install on a 107 with high flow air and no cat muffler. I'm only really interested in the guys that used a Thunder Max with a cam,. I have already done this combo and interested in a comparison to how you like yours compared to how I like mine. I'm having some speedometer electrical issues, my mechanic won't be back from vacation for another 8 days. I have 700 miles on the new set up.

I have a Thundermax on my 22 Stage 2 Street Bob and 24 Stage 2 Fat Boy. Both have Redshift 468 cams. 15K combined miles and no issues. Bikes run great....smooth power all the way to 6000 rpm plus plenty of low end torque..
Gas mileage decreased slightly due to a richer fuel mixture but bikes run cooler as a result.

I've never experienced any thumping or other unusual noises when accelerating. When I had my Stage 2's done, power and torque improvements were immediately noticeable.
Thundermax has several maps specific to the RS468. There has to be something wrong with your install and/or tune

Mine sounds like a baseie thumping noise coming from the air cleaner, it's actually kind of a cool sound. Low RPMs or high RPMs it doesn't do it. Only makes the noise going up a hill at steady speeds or a moderate acceleration. If I put my right leg tight to the gas tank to block out the air cleaner, I can't hear it. Still struggling with a gas gauge showing odd amounts of gas that make no sense. 5 more days before my installation mechanic will be back in town. I'm close to 800 miles on the new cam.
I'm going to stop riding it after tonight, until he gets back.
Thank you for your input.

Thanks for the advice, my mechanic will be back the 13th. I will have him get into everything and go from there.... I will up-date.
