Overland Tailor Tuning (OTT) - 4G (2024+) Tacoma Development

[JustDSM]

Would love to see comparison against actually stock OEM specs - aka 87 octane.
Anything more or less is a forced aftermarket adjustment distorting the picture.

Bring us a truck running the fuel you want tested and we’ll provide the testing free of charge.

This was a vehicle supplied to us. We can’t (always) control what fuel is used.

It should also be noted that this isn’t a “special” tune for 91 octane or premium fuel in general. Our Stage 1 calibration is designed to run regular to premium. What’s presented here is simply a data point.

I don't want to derail this thread, but I think it's likely that Toyota's published horsepower and torque numbers were obtained with premium fuel. I think @JustDSM has already posted a dyno chart showing a decent jump in power just from premium fuel alone (before any tuning). Yes, the truck can run on regular 87 octane, but it also detunes itself for the lower octane. Forced induction engines like higher octane.

Thank you for providing this clarity that the tune isn't forcing/necessitating a different fuel grade.

I'd happily coordinate to swing through if I wasn't a few thousand miles from your shop. If it was in the greater Baltimore area, I'd offer coordinating for the access to a LTD HV.

Please don't get any message wrong, appreciate your dedication to the mission of capitalizing on a design and seeking safe, sustainable improvements!
