Why? I can get cables and SEPST for $405 plus tax.

Even with all the work done to the kits that are self tunable every bike that is out there runs differently and will react differently to the kit put on it , elevation, oil type , exhaust, how you break in the bike , how well of a job was done in the build. port polished or not, A dyno is a tool and like many tools you can find your way around it but sometimes it is THE tool for the job. I just did a baseline dyno on my carb 883 and will do another after im finished with my conversion in a few more weeks. I dont really need to dyno my bike but it is a good tool to show engine health and to really know what your hard work and money has done. in my situation there will probably be no benefit to the dyno other than for a little peace of mind about what I have accomplished
Whatever floats your boat. Just because I don't go for **** doesn't mean I look down on those who do.

I looked at the fuelpak FAQs and see that it doesn't adjust the rev limiter. Not sure how important that is. What it doesn't adjust that I think is important is ignition timing and idle speed. Also, as they say at the FAQs, the modes are controlled by V&H. Thanx but no thanx. I want to be able to tell the tuner to adjust certain things the way they should be adjusted and not have a "black box" situation.

Default SEPST tuning parameters

Air Fuel Ratio
Throttle Position
Spark Advance
RPM Max
Idle RPM
Accel Enrichment
Decel Enrichment

Reason I would consider the PowerVision is that I believe it can control those parameters just like SEPST so if it can control those parameters and more, I would be interested. However, as said by Fuelpak, it cannot.
