You stay in the driver’s seat
Perfection is our passion. Our commitment to you is to keep tuning until it is perfect — not just via mapping, but by putting the right products behind that tune as well.

Flash & datalog
You receive a base calibration for your setup. Drive it, log it, and send the datalog back to your tuner.
Revise & report
Your tuner reviews every log and returns a revision with a full written report of exactly what was changed and why.

Repeat until the AFRs are stable, the knock is gone and the throttle response is where you want it. Then we follow up down the road.
The E-tunez advantage
Experienced tuners, no secrets
We have been e-tuning since the name was invented, and our tuners have been working with tuning solution developers since their product release date — in some cases before. Every one of our tuners owns and drives the same vehicle they tune for, and all of that experience is made available to you.
Some tuners would have you believe your engine is so complex that you simply can’t comprehend the tuning process, so just “trust” it’s done right. What if it’s not? Do they follow up on your tune down the road, and will they re-tune for free?
-
They drive what they tune
Your tuner owns the same platform you do and can back up your tuning solution with the know-how to make it run right.
-
Full written reports
We openly share our tuning techniques and tell you what was done in a full textual report. We believe there should be no secrets.
-
Free help, tune or not
Datalog review and tuning suggestions are free. Even if you don’t buy a tune from us, we will still help you resolve an issue or better your tune.
-
We follow up
We keep tuning until it’s perfect, and we check in down the road instead of disappearing once the invoice clears.
Testimonials & reviews
Straight from the drivers
Real words from real customers. There are plenty more on the reviews page.
I’ve had a great experience with E-Tunez. Richard was thorough and responded very quickly to all my emails. He was a great resource to have through the process and answered any questions I had. It’s clear Richard cares about delivering quality tunes and takes pride in his work. I would highly recommend and will be a returning customer.
Dan made my tuning experience with him an absolute pleasure! We fully tuned my Acura TL Type S for E85 and 91 pump gas as well as pop tunes for both fuel types. The car pulls very hard and I have no question in my mind about the reliability. Dan was very transparent during the tuning process and notified me about EVERYTHING he was adjusting as well as giving me advice and answering all of my questions! His knowledge is unmatched.
Working with Richard @ Etunez was a breeze. Revisions were sent back in a timely manner, my tune was finished in just over a week. Every revision felt different than the last — more power, driveability and increased gas mileage. No hiccups, the throttle response is spot on, no knocks, AFRs are perfect and stable. I was hesitant at first of an Etune, but I was left assured that the tune is in good hands.
I daily a 9th gen Si with a K-Tuned 3.5in SRI, 3in Full Race exhaust and RV6 catted downpipe. The experience has been great — feeling the difference from rev to rev has been awesome. I feel more connected with my car now, if that makes sense. Driving is smooth and the added performance is felt throughout the powerband. If you need a solid tune, look no farther.
Thank you so much again Richard for all your help. The car sounded and drove smooth as a kitten throughout all these events. I will recommend you guys to anyone interested in an E-Tune and will certainly come back if I install any new performance mods. You guys are awesome.
Car is much more fun to drive than it was stock, and I’m looking forward to continuing this build. Looking to get coilovers next, then get into the motor hopefully sooner than later. Will need you again when that happens.
