FREQUENTLY ASKED QUESTIONS

Does my Engine/Trans ECU software need to be updated (Toyota Service Bulletin TSB)?

We will verify your truck’s software version and update it for free if required.

Can the dealer detect my tune?

Our ECU Flashes do not modify the OEM ID, which means it will always report back as "stock" when the dealer reads your software version. Although we do not guarantee warranty status, many of our customers have had no issues having warranty items taken care of without issues after tuning. Tuning your truck should not be considered different than any other “aftermarket” modification.

Can you calibrate my speedometer?

 No, check out other aftermarket options available such as Rough Country or HyperTech.

Will this void my warranty?

 If the warranty issue in question is caused directly by the tune, you could potentially have your warranty voided on that item. These tunes however are 99.9% undetectable by the dealership. We make no guarantees or promises that tuning will uphold your vehicle's warranty, HOWEVER many of our customers have had their trucks at their local dealership with no warranty problems or issues. Please use your best discretion when considering tuning your vehicle.
