Jb4 Burger tuning F90 meth injection.
Hey old friends!
My car is in the shop for meth injection through Jb4 (burger) Has anybody added it yet. Would love to talk about how works. How to setup the maps.
What type of fuel works in conjunction. Meth water ratio?
Performance addition?
How it actually integrates with the jb4 connect kit
If anyone had any numbers as far as quarter mile and 0 to 60
