Problem is- neither would be perfect for your mods.
If you brought your bike to guhl's shop- I am sure he could put his tune on, and then adjust it on the dyno but that would take a road trip and more cost than just the reflash.
When you say 'custom map' on your power commander- who made it? They had YOUR bike on a dyno with an exhaust sniffer while tuning?
A power commander w/ supplied tune is fine for say a slip on muffler.
It will *run* with more mods than that- but if dynoed you will see the af isn't perfect. Just adding the TSR airbox plate with a staintune muffler and power commander file on my bike leaned out up top more than I would want to leave alone.
The power commander with the optional autotune box will adjust fueling to your desired a/f for your bike, with your mods, all the time, all weather, temp, altitude, barometric pressure, etc.
Problem is- it only does fuel.
Guhls flash adjusts the ign timing advance, gets rid of the speed limiter, raises the rev limiter, gets rid of the 1,2,3 gear limiters...but, like just the power commander alone- his file is 'static'. Unless he tunes it for your bike- it won't be ideal. And even if he did- it won't adjust for all the stuff I mentioned above.
Best solution is power commander + autotune + guhls box.
