What’s on the dyno? 2025 Gen2 Roadglide 117. Nice stage 2 with Fueling 534 cam. With 10.2 compression and 31 closing. Cam’s a ripper for a nice cool running engine w/ out stacking compression. Tuned with TTS.

Not all replacement spark plugs are created equal. I stick with stock plugs on my M8’s. I’ve tested and seen plenty of flashy aftermarket plugs promising big power gains, but none of them have ever lived up to the hype.

If you have outgrown flash base tuners for your ride. (Stock ECU tuning) I suggest skipping the hype and getting into a full-blown programable ECU. Full control of anything you can think of.

Another M8 Harley plug and play MaxxECU Sport setup with nitrous control, fuel pressure, and air shifter, stock dash, body control module, hand controls etc. all integrated in.

Nice before-and-after comparison.
Somebody else’s cam choice vs. my cam choice.

I research cams the hard way — by testing different camshafts, cubic inch combinations, and exhaust setups, then tuning them on the dyno and proving them with real-world road testing.
Others just read someone else’s research.
This page is all about promoting C&S Speed Shop — not cam manufacturers or anyone else in the industry. With over 30 years in this business and 18+ years running my own dyno and shop, I’m still just as excited to do this every day and make a living doing what I love.

My first MaxxECU install on a shop bike. This is the bike I defined all sensors, discovered proper internal timing and set all tuning tables with. Others just cut and copy my tables.
