WHAT MAKES THE TFI BETTER THAN THE OTHER TAP ON UNITS

With today’s ever-growing number of applications and bolt on performance products the need for fuel injection control is very important. The performance barriers of yesterday are the baseline for improvement today.  With all the thousands of performance combinations that are available to the public there is a growing demand for more flexible fuel injection controllers.

One of the key features of the TFI over the rest is the FOURTH POT adjustability. This feature allows for many different engine combinations to be tuned properly at certain RPM’s. 
For example:  Increasing displacement and camshaft profile changes the engines power curve thus changing the need for fuel at a certain RPM.  Here is where the FOURTH POT becomes a necessity.  Without this feature the tuner is confined to adjusting fuel on a stock power curve with no room for adjustment at a certain RPM.
So why spend your money for stock adjustability when performance is what you want?
