See The Difference

” I ordered a Unichip Plug ‘n Play kit for my Toyota . When I opened the box I was shocked ! I expected a micro chip , what I got was a fully functional engine management computer , together with a top quality wiring harness to connect it to my vehicle . I called the guys at Unichip & they explained the whole system to me . The Unichip comes pre-mapped to optimize my Cold Air Intake , Headers & Catback exhaust . Two maps ensure optimal timing settings with standard & premium octane fuels , as well as the best possible mixture settings. I switch between maps via a special switch . On top of all of this I can have the system re-programmed for different bolt-on configurations . I can even have the system custom-tuned ! Installation was a breeze! Now that I have the Unichip system & I understand how it works I realize that all the other so-called tuning products advertised on the internet for Toyota’s are all just gimmicks ! They’re either small resistors which connect to the MAF sensor (with no power gain) or shady “ECU reprograms” which void your ECU warranty & provide no gains whatsoever . I recommend the Unichip to anyone who prefers quality parts on their Toyota & if you don’t believe me , do your homework & compare the Unichip to anything else out there , it beats anything hands down!” Jose F, Florida .
