Customer Reviews
Always reliable tuners
Got another Mini Maxx Diesel Tuner, this time for my new Ram. It's my third tuner from H&S over the years. Always a solid product, performs just like the last ones did. Shipping was quick too, got it in about 4 days to Florida. Exactly what I expected.
DPF delete kit good value
I was looking for a DPF Delete Pipe and an EGR Delete Kit for my Silverado. Checked around a few places, and H&S had a bundle that just made sense. It wasn't a huge discount, but that $75 off the combo made it the best option. Everything arrived in one box after about a week. Installation was straightforward enough, and the truck runs much better. Felt like I got my money's worth.
