Tuning allows us to get the most out the naturally aspirated FA24. With headers, quality flowing intake, and flex fuel, we can expect power figures of 236-239whp and 185-187WTQ on E85. ECU tuning optimizes the factory calibration to improve power delivery, throttle response, and overall performance while accounting for modifications.

Ecutek is the most widely used tuning device on the platform, allowing the GR86 and BRZ to be flashed with custom maps, monitor live engine data, and read or clear diagnostic codes. It is the starting point for most naturally aspirated tunes and is required when forced induction is introduced to account for the added power/air flow.

Under the Magnuson-Moss Warranty Act, a dealer cannot void an entire factory warranty simply because aftermarket parts are installed. A specific claim can still be denied if a modification is determined to have caused the failure, and ECU changes are detectable. Warranty decisions are made by Toyota and its dealers, not by LIMIT+1.

Yes. Tell us your vehicle, your goals, and what is already installed, and we will put together a parts list that works as a system instead of a pile of individual upgrades. Order matters as much as part selection, and sequencing a build correctly avoids buying the same part twice. Contact us before you order if you want a second opinion on a plan.
