Default M8 with cams and tuner

What tuner do you have with your cams ( and what cam) and why? What pipes are you using as well i have a 2018 SGS, with Bassani true duels, s&s 475 cams(actually did the full cavity, cam plate, oil pump, pushrods, tappits and tappit plates) and finally swiched from fp3 to Thundermax. Thank you in advance for your responses

I do not have cam upgrade in my bike, but I do plan on it. Right now, I just have SE Heavy Breather with RH pipes and PowerVision tuner. When I do upgrade cam and oil pump, I will have it tuned on a dyno. I will not rely on PV for that.

In my M8 (FXLRS) Tman 216 cam, AN big sucker, S&S superstreet 2-1, SE cam plate/oil pump, S&S lifters/rods/guides, and dyno tuned with PV.

OP, just curious, but why do you ask? You set up sounds like it should be awesome.

Running a Powervision tuner with a Redshift 468 cam and an S&S Sidewinder 2-1.

PV because it's better for what I did than the FP3. Though I'm sure the FP3 would have done a fine job. But in the end. I wanted to try something different. Last bike was a FP3 and I just put a FP3 on the wife's 2019 Freewheeler.

Redshift 468 was on my short list with the 475 S&S and the Woods 22xe. Friend is a Harley mechanic. And suggested the 468 as he had done multiple builds with UT and loved where it hit. I'm not disappointed with his suggestion.

S&S 2-1 because I had to run a 2-1. Want to get all that i can from the cam and S&S was on the short list with a Boarzilla and a FatCat but founf the tome.of the S&S to be more to my liking and the seat of the pants dyno won't notice a difference. But I've been told the Sidewinder is under rated and tunes as well as the top ones.

Don't know. I know I live the sound. Love the look. Love the way my bike runs.

Stuck with Screaming Eagle torque cam and SE Pro tuner for warranty. The rest is in my signature. I am very pleased with the sound and performance.

The true duals are going to kill your low-end. Not some much on a twin-cam but the m8 hates them

To maintain my warranty I went with the Screamin Eagle torque cam, tuner and ventilator air cleaner. I also went with Rinehart slimline duals. With a dyno tune I'm getting 100 HP and 124 ft/lbs of torque out of my 107. That's plenty for my fat old ***.

I hummed and hawed about the exhaust because of my warranty but I trust my dealer and he said that down in the US there is the odd dealer who will be ********* and flag your bike for aftermarket exhaust, but he has never heard it happening in Canada. I'm confident they will look after me one way or the other.
