I have the JB4 with a catless Titan dp. I’m running a MHD bef with the JB4 for better overall performance and to not get a cel or even a shadow code. I would suggest Titan as I had others in mind a few months back and went Ritu Titan because honestly, it’s just a pipe and paying over $300 for...

Don’t go to the dealer. I hope you did a log. Reach out the BMS. Your car is in limp mode

I too made the same mistake and had to re tap. But I didn’t screw in all the way through

Get a 2020!

I currently run the JB4 with a MHD bef and for starters. It’s a totally different car now. once you bef the car, you go into JB4 and toggle bit6 so the JB4 knows a bef map has been loaded. The biggest advantages you will notice with the MHD is better timing and fuel adjustments. the bef will...

Put your foot on the brake and rev it in neutral

My manufacture date is 7/19

Funny how Toyota won’t release the Supra in need for speed games because they “don’t want to associate themselves with street racing” but then they make this commercial…

When the JB4 is installed. Make sure that there are no loose wires hanging about and that the ones in your engine bay are away from heat and zip tied. with the exhaust, make sure the tips arnt touching the plastic at the back of the car. You don’t want burnt plastic. Expect a possible cel code...

I will have to look more into this. Havnt seen it mentioned and it’s a good price but lower than others which makes me question it.

You’ll be fine with stock chargepipe. I’m only asking because I’m making +20 /22 over stock

I am looking to upgrade my charge pipe to prevent damaging anything due to the amount of added boost to the car. I have looked online to see what is available and searched the forum for any info but see a lot of people say that the pipes are getting undone.

I’ve tried using a lot of force with my hand to pull the JB4 connector out of the OBD port but don’t want to risk breaking either connectors. has anyone had this issue and know how I can safely remove it?

The inlet was the easy part. But everything after was poorly designed. I went off the listed instructions and they were very poorly made. if anyone is installing this, screenshot these notes. 1. don’t tighten the lower ring to the inlet until you feed the top pipe into the heat shield 2. All...

More surprised at the clean garage

Does the Supra have PTFE fuel lines? If so, why are people buying flex fuel line upgrades and not a HP/LP fuel pump?

Yeah dm me so I’ll remember
