jb4

This convenient factory grounding stud is where I grounded my methanol pump, solenoid, and fsb. Also modified and painted a random bracket I had laying around and attached on the same stud to provide a little mounting shelf. You could drill a few holes in any small L bracket and do the same. I...

Just bought a JB4 tune for my late production 2021 Supra. Apparently since its a piggyback system it can get +80hp gains without touching the ECU. Is this the only route we can go from now on until they are unlocked? Currently running just an mst intake and planning on a Frequency Intelligence...

I'm in the process of picking up a 2021 3.0 premium and won't be able to tune as the ecu is locked. I plan to get jb4 but would like some other performance mods aswell. I know tires and running higher octane fuel is possible but what about dp, exhaust, pure 800 etc What can I do to improve the...
