Not sure I like to be a “beta” tester.

What were you able to accomplish with it??

Turned off the seatbelt chime, turned off the fake engine noises, allegedly set the seat ventilation to high vs normal, and one or two other small things.

Looks like JB4 Map 2 = 0-60 in 5.9 seconds and 1/4 mile in 14.3 seconds at 99 mph. Not bad for a 5,700 lb AWD beast LOL.

Pretty quick for sure. Heck a GR86 is like 14.0 flat with a good launch.

Wish there was a non-piggyback option though .

Yep they do. I’ve also been running their system on my Supra in tandem with an ECU tune for the past 4 years without issue.

It really does produce good results as long as you have enough octane. 93 octane is required / highly recommended for Map 2.

Glad to see another Supra brother. I had great results with the JB4 on map 6 with a tailored tune. No problems ever.
