2.5T Stinger JB4

[CadenY]

Hey! Just picked up my 2022 Stinger GT-Line! I was familiar with the JB4 on my Supra but I’m new to it on the stinger platform. I was hoping to see if anyone has a 2.5T Harness JB4 for sale for a reasonable price? Also what’s the hp bump for map 1? Is it worth it? Anyone have any problems with running it?

Also what are the thoughts on LAP3 tunes? Would this work for my stinger since it’s the same motor as the K5 GT? Do you get more power out of it and is it more safe?

I would appreciate the help! Thanks!

I’m in the same boat, looking for a JB4 for my new/used 2023 GT-Line. It looks like BMS shows roughly a 30 hp and 37 tq bump on map1 for a 2.5T from a genesis suv. They don’t show an output for map 2, but based off of the graph for map 4, I’m guessing map 2 would probably add another ~10hp/10tq to map 1.

Don’t know anything about LAP3, since it doesn't appear many have run it, based on these forums. The JB4 sounds like it has a good track record since I haven’t seen any engine failure threads from it, unless someone else can chime in here.

I have all the numbers you need. I'll update this once I get to my computer later this morning.
