Has anyone tried this, claims are increased horsepower, torque, and lower egt's. are these claims true, will it void the warrenty ? Cost over $600 dollars.

Any performance module will delete your warranty.

Find out how it works. Pressure boxes connect to the fuel rail sensor and map sensor. Too high of pressure is bad. If you are looking for just a little more power there are more economical boxes out there. Check out a smarty or smarty JR. They are a programmer. They also check codes, enable fast idle, etc. Fill out your signature so we know what kind of truck you have.

That product really improved perfomance, not true mileage. After 30k I noticed mileage going way down especially when towing. The extreme pressure caused me injectors & nozzles. I've since replaced the injectors and nozzles with DDPs and gone with a product the monitors the important stuff. Much happier, and mileage has come up.
