Both can make just about the same engine tune adjustments. Here's several key reasons to choose one or the other:
- which one can you get the better purchase price
- which is your local tech that works on your bike, more familiar with.
- if you ever plan or need to make adjusts to your tune on a trip or ride, you can only make those changes through the PV (it can be in a saddlebag if you prefer not to mount). In order to make any tune adjustments with TTS while out on a ride, you'll need to bring your laptop with you.

There was a reason the MOCO to removed the oil reassure number and replaced with a go/no-go message.
There was a reason back in the 80's the MOCO removed the cylinder head temp gauge on its TourGlides.
Unless the general public knows and understands the data being displayed, they can and do panic when they see something that doesn't look right to them.
Some shut down their bike and have it towed to a dealer and some get home and start calling and posting asking for advice from some who have less experience than themselves.
As Harley tells their customers, ride your bike knowing if anything goes wrong they will fix it.

Just curious, what does knowing the engine temp do for or to your riding experience?

The PV display is also a great device for observing the tuning process directly on the bike. If you're not familiar, having a PV allows you to autotune while riding. The PV will display a grid of rpms vs VE so that you can alter your riding, load, speed, rpms etc to fill in more of the tuning grid for a more complete autotuning of the engine under all types of conditions. You can't observe how much of the engine map you are collecting data for WHILE riding and autotuning with TTS.

The TTS stores both the original settings and the current calibration in the module. You can also store them on the TTS web site for safe keeping. Then any laptop or PC will do the job for you on the road.

Sure TTS doesn't have a catchy less than gps sized screen to monitor. You however can monitor tuning using a smartphone, tablet or remote monitor either connected or networked to your laptop. Myself as well as many others have done this many times.

All true. I was just responding to the OPs ask about the differences. If you plan on autotuning while viewing the actual data collection to ensure you're capturing all areas of map data, then the PV is a simpler and less costly alternative. TTS will require bringing a laptop with you to view the data and flash the revised map to the bike. All of that capability is self contained in the PV. No laptop. No synch to a phone.
If you have no plans to autotune and aren't interested in viewing bike metrics on the screen while riding, then go with the tuning product that your local tuner is most familiar with and the best price. Both systems will generate equal tuning results in the hands of a knowleadgeable tuner.

One more thing, where do the different tunes reside on the TTS website and are they general or specific. For instance my bike will have gutted cat with 4" rinehart slipons and high flow intake. Is there a tune for this particular setup or is it more of a a general Stg 1 tune. BTW, its a M8 107
