Emira JB4 Tuning Now Available for I4 & V6 Cars!

[GRP]

I hadn’t heard of JB4 tuning before but a quick google review has really good things to say about them and they’ve been around for a while.

They have been around for quite some time and are tried/true
When we initially heard they were considering doing tuning for these cars we contacted them immediately and did everything we could to help, including a good bit of persuasion to do the V6 cars.

Ordered! Excited to try it out. Little nervous of the install as I haven’t really messed with the car much. Any written instructions on how hard this will be to install?

Written instructions are coming asap.
They are working on the write ups for them and we will post just as soon as we get the word!
It’s all plug and play, “T’ing” into various sensors and their connectors/harness.

Greg, would you know what the BETA status means in terms of support?

I'm coming from the supra community where everyone did jb4 until they wanted to drop 5k for unlock/tune or just sell them afterwards (resale value is pretty good)

for warranty its really up to the dealership. It looks like enough people here will order it and hopefully half of them will post reviews/videos for everyone else on the fence still

For anyone that wants to keep their car as stock as possible, this seems like a great option though since multiple vendors have stated anything close to 500hp becomes unstable.

I was assured today that they will have full support and everything is fully functional. There may be updates with software or tuning later one but that will be all updateable if it happens.

For sure. We will share any videos/media here from installs, draggy results etc.

[95whp increase on the V6 powered cars!]

Understand how to squeeze more HP out of a Turbo car, but how is it really possible to push 25% HP out of a supercharged engine without changing the pulley or significantly reducing the charge temperature.

I replaced the pulley on one of my supercharged cars and didn't get anywhere near 25% more HP. What am I missing?

Yea I’m also curious how they extracted so much power without a real tune. I used to have an Audi s4 with the 3.0 supercharger and it was annoyingly expensive to get more hp out of it (which prompted me to switch to an M3 lol)
