JB4 vs JB stage 1
I need help which product will serve me better as my 435 is almost here. I'm not doing any mods besides the tune. Is the stage 1 simpler to install/uninstall and use? I don't need a laptop because I'm not checking codes or switching maps, right? I'm a total novice and need to trust myself when uninstalling in case something goes wrong with the car (related or unrelated to the tune) and having to take it to the dealership and in turn, reinstalling. I have an excellent tuner that I'd use for the initial hook up or any problems I might encounter.
Many thanks guys
