a go/fail test procedure. Only once they pass all the tests,

then only do they enter the next phase. All our products

re-tested to make sure there are no component failures.

This process ensures that the product you buy will last

longer and give you years of service.

programmable fuel injection and ignition computer

systems. High speed communication is achieved

from USB communication. LetRipp II tuning software

is used to manage the tuning, in real time, with all of

our modern tuning units. The software was designed

with tuners in mind and has many features to assist

in the chip tuning process. All our products have

extensive help documentation, application notes,

FAQ's, and manuals that will answer almost every
