I use the tweecer, and love it.


PMS is also highly regarded.


The tweecer is said to have a tougher learning curve.

The pms is said to be quicker to pick up.

Either way you still have to take the time to learn the basics of tuning an efi car.

what is the easiest to use?
does anyone know anything about the FRPP EPEC?

There is going to be a learning curve with ANY tuner.

The things you will need to do when tuning are not things that most folks think about, ever.

Regardless of which system you go with, it will be challenging for at least the first couple of weeks.


never heard of that Ford tuner.
Maybe it is OBD-II specific?

I never realized those Tweecers were so expensive ($350+). Then you need a laptop to tune the car, right?
