OTT Tune vs. KDMax for a Toyota Tacoma
Where each option stands today
| Option | Status today | Install model |
|---|---|---|
| KDMax Pro (Tacoma) | Discontinued — not distributed, no further adjustments possible on existing files, per the maker's own FAQ | Sold as a mail-in / flash calibration |
| McB's Elite Performance (KDMax's successor product) | Current product from the same site, described by the maker as not a version of KDMax Pro | Not evaluated by Tuned Yota |
| OTT tune (installed by Tuned Yota) | Active, dyno-verified, ongoing platform support | In-person calibration by a licensed VFTuner PRO Tuner at a Midwest event |
If your Tacoma is already running a KDMax Pro file
- Per the maker's own FAQ, no further adjustments or source-code changes are possible on an existing KDMax Pro calibration.
- The site that operated KDMax Pro now directs new customers to McB's Elite Performance instead — a different product, not a version of KDMax Pro.
- For a Tacoma being tuned today, the OTT calibration is the active option with ongoing support and updates.
What the OTT tune adds on a Tacoma
Every OTT calibration is built in person by a licensed VFTuner PRO Tuner, factory emissions systems stay fully intact and 5-gas verified, and the results are dyno-backed rather than claimed. See the full Tacoma dyno chart and platform details, or the Magnuson supercharger guide for the ~362 whp forced-induction path.

No. KDMax's own FAQ at kdmaxprotuning.com states that KDMAX Pro calibrations "cease to exist and are not available for distribution," and that no source code or adjustments are possible on existing calibration files. The site now points new customers to a different product, McB's Elite Performance calibrations, which it describes as not a version of KDMAX Pro.
According to the maker's own FAQ, KDMAX Pro was discontinued and is no longer distributed. Owners running an existing KDMax Pro file cannot get further adjustments made to it. The company that operated KDMax Pro continues under a new calibration product, McB's Elite Performance, which it describes as unrelated to KDMAX Pro.
The OTT (Overland Tailor Tuning) calibration is an active, ongoing platform-specific tune for the Toyota Tacoma, installed in person and dyno-verified by a licensed VFTuner PRO Tuner. Tuned Yota is an authorized OTT installer and continues to support and update the platform.
A real Dynojet pull on the 3.5L V6 Tacoma shows about +9 whp and +11 lb-ft over stock at the peaks (roughly 246 to 255 whp, 240 to 251 lb-ft), plus a fuller midrange and smoother delivery. Supported Tacomas running a Magnuson supercharger reach roughly 362 whp.
Yes. Factory emissions systems stay fully intact, and every OTT calibration is verified with a 5-gas analyzer during drive-cycle testing, EPA-compliant in every state.
KDMax Pro is no longer an option for a new calibration — it isn't distributed and existing files can't be adjusted further. For a Tacoma being tuned today, the OTT calibration installed by Tuned Yota is the active, dyno-verified, emissions-intact option with ongoing platform support.

KDMax Pro's discontinued status is sourced to kdmaxprotuning.com's own FAQ, current as of September 2026; that company may update its offerings independently of Tuned Yota. Dyno results are specific to the platform tested and vary by vehicle condition and setup.
