Allow me to give you some general info here
I have had a good bit of experience with the Tweecer and none with
the Pro Racer Package. I've seen many say the PRP is really nice and
what little I've looked at it ... it seems really user friendly.
Sooo ... having said that
Both tuning interface packages will give you good results
I have not had any issues with my Tweecer reseting itself
The Tweecer offers real time datalogging which can be so helpful
If you really want to be completely stand alone with everything
you need to tune under ALL conditions you will need a wide band
with either method of tuning interface.
Nice wb's can be had for two to three hundred dollars
One option with the Tweecer is you can go for just a basic featured
wb cause you can output the wb to display in the data logs.
The need for a wb that will capture data and play it back is then
not needed thus saving you a bit of money
