    No. And Even if they did you wouldn’t be able to do anything about it. The 5vz ECU is hot garbage and cannot be tuned. And the aftermarket has failed to produce any meaningful solution besides a piggyback or a full $3k standalone setup.

    I’m using denso fuel injectors from an NA Supra and no noticeable increase in power but it does help with leaning out from my supercharger. I also added a URD FTC and helps with the ping again from the supercharger. I have a 2.2” pulley that will go on as soon as I get my clutch and lightened flywheel on.
