The E-Tunez advantage

Enthusiasts first. Tuners always.

We’ve been e-tuning since the name was invented, and our tuners have worked alongside tuning-solution developers since release day — in some cases before.

We do things a little different

We don’t just want you satisfied. We want you leaving here saying: terrific service, commitment and pricing.

That means affordable tuning, quality support, and a tuner who not only drives the same vehicle you do, but can back up your tuning solution with the know-how to make it run right. Eventually, we’d like e-tunez.com to be your one-stop shop for everything it takes to get your car running “just right.”

Why our customers stay

01

We share everything

We openly share our tuning techniques and send a full written report of what was done. Your tune shouldn’t be a black box.

02

Free advice, really

Datalog review and tuning suggestions are free. Even if you don’t buy from us, we’ll help you resolve an issue or improve your tune.

03

We follow up

Some tuners say your engine is too complex to understand — “just trust it.” What if it’s wrong? We follow up down the road, and re-tune.

E-tune or dyno-tune?

Both beat a basemap. Together they’re best.

A full top-to-bottom dyno session can run 8 hours at $100–150+/hr. With modern OBD-II, roughly 90% of the work can be done before you ever strap down — averaged over real-world conditions instead of a single afternoon in the shop.

Get a quality e-tune first, then if you want those last few degrees of ignition, your dyno tuner can spend the time on WOT instead of fixing basics. That saves you time and money.
