Problem with the jb4 and my 1m
So recently i just installed my jb4 back into my 1m bc my car is full bolt ons now. I have the ess stage 1 tune and it has worked great but i bought it bc my jb4 is spiking boost and dropping really low in map 2. Idk whats wrong with my car or the jb4 but i just took it out i updated to the new firmware but i dont understand whats wrong
