C450 aka fake c43
you my friend need a intake system, i recommend CTS sounds and performs amazing. That’ll fix your ‘real estate’ issue.

What kind of numbers are people getting with their jb4?0-60,1/4, 60-130?
I just put it on my ‘20 and it “feels” better than it did on my ‘19. Will try to get some 0-60( I know that is highly based on launch & tires blah blah) but I really want to be 3.6-3.7.
I couldn’t ever get improvement on my ‘19 0-60

Personally have my fuel and duty bias set at 100 all the way through the rpm graph, also have my boost target at 25 for every option. There’s also a setting you can adjust where it doesn’t cut boost when the car shifts. Stock its set to 60 I have it at 0. Cars on e50 mix feels like a bat outta hell.

Just got my DRAGY yesterday. Can't wait to see what I can do with my JB4 too. Anyone see the new bms yt vid? They were able to get a beat up KIA Stinger to 485rwhp & 600lb ft of torque with just the JB4 and some e85...I wonder what kinda #s our jb4 c43s are making? But they also kinda cheated ... apparently u can just pull a fuse & disable AWD...those were rear wheel #s.
