No more tuning CB1100??

You will get more benefit in power and a smoother running engine from fueling than from ign timing changes.

Since the power commander does fueling and is still available- get it while you can.

Once you have it- the only difference Guhls tune would add is higher rev limiter, top speed limiter removal, rumored ign changes in lower gears (unverified) and a general ign timing change overall which nets about 3% gain in peak power.

You won't feel 3% on the seat of your pants.

If his tune was still available- yes doing it would give you fuel AND ign and would be worth it... I am just trying to say you can still get very close to the same with a PCV
