Engine Upgrade
What’s the largest I can go on my 07 Electra Glide Standard that will still work with my stock ECM? I know a 103 will work no problem but curious if a 107 or 110 will work with my stock ECM and a tuner of course??

To my knowledge doesn't matter how big the engine is, the tuner tunes. Maybe some monster builds are so far out of parameters?? If I am wrong, some will say so. But boring to 103 will be fine,

The simplest and largest, without a ton of custom fabrication needed and run off your stock ECM would be this....

I didn't go that big...
FWIW...
I put a 124" FuelMoto Street Outlaw, S&S crate engine in my 2016 Ultra Classic. It bolted right in... however...
I needed new throttle body, fuel injectors, air cleaner, exhaust, the special S&S oil line installation kit, as well as gaskets and fluids. Then there were a few drivetrain upgrades to put the new power to the ground.. heavy duty clutch spring and variable pressure plate, plus gaskets and fluids...
It was tuned using my PowerVision Tuner and the OEM ECM....
I ended up with 135HP & 151TQ... it's a blast to drive and my main touring bike. It's solid, and reliable.
My last group ride with several friends lasted 6 days, totaling 2.2K miles. With very little playing around with the throttle, I averaged 43 mpg...
I'm quite satisfied...
