Been using this product for years. Two 94 GTs and now on my 04' GT. Never fails to increase performance as promised. Would buy it again...Thanks
When it comes to tuning your ride, sometimes you need to make adjustments on the fly, or maybe you don’t want to lug a hand-held tuner wherever you go. For those times, you need an in-line performance module. In this guide, we’ll tell you what they do and why you need one.
Know before you buy! Read customer reviews about In-Line Modules or ask our Product Experts.
Deciding to add more power to your ride isn’t a difficult decision. But, deciding if the pros outweigh the cons can be tricky. That’s why we make it easy for you by outlining all of the pros and cons of performance chips to help make your buying decision even easier.
