Guhl and 1973CB are both out of business as are any ECU reflashers and there is no alternative. It is what it is.
You might contact Powerdubs for advise, but in all honesty the CB is limited on what you can do with it. If you want more ponies in a retro bike you might try the Kawasaki Z900RS
Regarding 1973CB... it appears he and his friends are making money elsewhere selling the tune I shared ...which honestly ticks me off.
I bought the cables needed- and ripped the file for the benefit of the community.
I gave it to him for free. When I saw what they were doing- and called him out on that... he did what any other bad actor does...make excuses to justify their greed.
He said it was OK since he had to pay for the file that allows him to read and modify the software...which is deflecting.
I paid the the Guhl flash itself...by his logic I should have charged for the file I gave him....I paid for the cable interface to send him the file...heck, I could have done the same as him and resell the file instead of giving it out...I didn't need to even send it to him....but I did it out of my own pocket, my time.. for the community.
*THUMBS DOWN*

Eh... I wouldn't call it limited any more than any other vehicle is limited for whatever it is.
If we changed 'what' this bike is.. a LOT more could be done with it.
Most any vehicle gets a decent gain from basic mods...and then needs to go further in extremes for the last few %. With trade-offs.
On our bikes- getting 20% more power is easy..simple intake/exhaust and fuel. No trade off.
I've approached 25% gains.. but cams are outside what most people will do.
The numbers I show are still with the stock airbox horn in place. If anyone remembers- I dyno tested the TSR box plate...back when I just had a slip on muffler and no way to add fuel. It did make a gain.. but went a little lean so I took it off...and just never bothered to put it back on. I'd expect a few more whp with it now.
I don't think I have hit the limit yet.. of even simple stuff.. I've got some parts, ideas and my dyno now...I've just spent the last year doing house projects...covered in sawdust instead of motor oil.
There should be several more ponies that are 'easy' before it gets to the stage that will be expensive and time consuming- (Mark is correct)-
Expensive and time consuming would be- port a cyl head, raise the CR a bit- both to make up for overlap and the Honda 'overly safe to run on ANYTHING' warranty protocol..instead of premium.
The good thing would be- those don't change *what* the bike is- they just cost $$$$ and quite a bit of work.
If we change what the bike is- possibly see if larger valves / more aggressive cams make sense... but at that point I might as well do bigger pistons as well...and... probably not.
I say probably not- because everything I did on this bike was to make it better- for what this bike is.
I could put an obnoxious exhaust on it and make another 1-2whp. I won't.
I could remove the airbox and just run open horns for peak 1-2-3whp. I won't.
I could cam it up so much that I gain peak 8-10whp but loose 15-20 down low. I won't.
....and I could still sell the Guhl file.. I won't.
