I have installed two of the Rev Performance EMS units on bikes in the last month. Both were somewhat mild builds (big bore 107 and 98) with torque style cams, 9.5 comp. This system worked extremely well on both scoots, one customer says it's the best his has ever run since the motor work was done almost two years ago.
On an additional note, I would agree with Warren888 in his praise for the Power Vision. I have had one for a year and it is a top-tier device and only gets better by the month as new enhancements appear. I've also had experience with the PC (both PCIII and PCV, with and without Auto-Tune), and can vouch for their ability to do the job. In fact, IMO the best value in tuners for many riders is a PCV with a Fuel Moto map installed, as it is fully tunable and can accept an Auto-Tune module later if desired. I used the PCV for a year and the PCV-AT for two years, and will attest that both configurations work as advertised.
The OP and others with pre-'07 bikes without O2 sensors should also note that if they decide on an auto-tune device (e.g., PCV-AT, T'max, EMS, or PV) they will have to weld two 18mm bungs on their exhaust system for installing the O2 sensors. However, if they have aftermarket header pipes they may have these already installed.

I never said Fuelmoto doesn't give good service but he pushes PC , I had one on my last bike and it worked ok but after having a TTS Tuner on this bike I much prefer it , Wes at Cycle Rama who did my build sells both PC and TTS tuners , I had him choose which tuner he wanted to use and he chose the TTS and explained why it was better , my friend had his bike done by Doc's Performance tuning and he uses TTS, call Wes or Doc and they will be glad to cover it with you , do PC work , yes , it did on my last bike , are they the best , no , does Fuelmoto give good service and his products work , yes , does his systems out perform others on the market like he'd have you to believe , no , I've seen dyno sheets from independent shops with his system on a bike and then other systems on the same bike and his systems were good but often not the best , I am not saying his systems do not work but many believe they are the very best available and this is not true

It might be worth noting here, for the benefit of anyone thinking about buying a tuner, that the Rev Perf EMS is not user-tunable. IOW, you get what you get and there are no means for adjustment if you should want or need it. Some will not have a problem with this but others will like the ability to make adjustments either inside or outside the ECM's parameters. That said, I've heard no complaints about it and it undoubtedly works as advertised. You must send them your ECM for reprogramming, and IIRC it cannot be retrofitted with the stock configuration if later desired.

I have many questions about the auto tune. What AFR do they tune to? Do you input the afr desired? Will it change the timing as it auto tunes? Will it sense ping? Does it have heat management cylinder shutoff? If a guy has heads from one place and cams from another and a hpi tb w/5.3 inj , will there be a map remotely close?

Most autotnes allow the user to input the AFR valuses to what they want in the areas they want them in. No autotune has the ability to adjust timing (beyond the scope of the stock knock control). Which will just retard timing if it detect pinging. MAP's are another thing that is subjective to the unit you purchase. PC has a pretty good selection of MAPs for the PCV (5). The Vision does not have the capability to autotune (since it is a flashed based tuner). You will see that it lists the autotune module as an option, but it would just allow you to data collect with it and manually make adjustments. ALL companies that sell autotune will actually recommend you have you bike dyno tuned before running the autotune. They might not advertise it but if you call the tech support lines that's what they will tell you.
