My mom has an 02 GMC Sierra, that is going to be mine soon. The title is already signed over to me. It has the 5.3, and this looks like a good mod to put on it. The truck is in excellent mechanical shape, but it has a bunch of dings all over the place because she’s a terrible driver. I’ll still take it though.
Hey that’s great!! ~ Michael (507) 215-3817 The Wave has been proven to be the BEST mod you can goto with any engine when you have your hands on it. Nobody gets you the results in fuel efficiency like we do! We are currently adding a 10ML Engine Treatment in every Wave Package 🌊 The Wave transforms ALL the unused fuel (pollution) into usable POWER and you’ll notice something amazing happened when you tap that pedal 😎 Smell the exhaust coming out before (engine warm) and get ready to get your mind blown with the reality of CLEAN warm air coming out the exhaust after the mod!! Most say it’s just like a dryer vent 🤯 Give me a call or place your order by clicking the link below 👇🏼 www.greenautotechnology.com/product-page/throttle-body-modification
Will this fit on an 02 4.3 ??? GMC Sierra. I've cut off the butterfly wedge. I run no alcohol gas and have a hypertech tuner on it. Always has the black tail pipe & smells like crap. I get the EPA rated mileage, but I know it could do better.
