Sorry the existence of this product has seemed to so drastically hinder the well being of some of you guys
To clear the air a bit - We recommend a tune for anything,
especially when adding boost. We wrote the book on most things Hellcat and our number 1 priority is not harming a car up when it comes to installing parts, putting builds together, etc. We can never guarantee anything that has anything to do with your vehicles warranty, nor would we ever take on the full liability of the life of a modified vehicle. Welcome to the world of performance and aftermarket parts ladies and gents, some of you may be new here
.
That being said; some pretty extensive testing was done by the manufacturer with this product, and the guys at Litens aren't a group of kids re-branding a product in their garage. They're a team of engineers and professionals with the same level/grade of equipment to test these things. There's a reason Chrysler chose to have them manufacturer the pulley that comes on the Hellcat platform vehicles from the factory. With that all considered, we trust their testing and their claims, but you bet your butt it'll be safer with tuning.
All of that aside we're one of the largest parts distributors in the Gen 3 Hemi market. If there's a decent product that exists we try our best to carry and sell it. We've sold quite a handful of the 3.17" units so I'm surprised more folks haven't put up more results with them - though there are exponentially more folks posting on Facebook groups than there are forums. If we come across any additional results we'll be sure to post them here and we'll have our own results here shortly!
