Is there 100% confirmation that previous tunes can be detected?
I've been reading all of these tune posts and it seems like someone gives a confident answer someone else rebutles it..so once the factory tune is restored do we know 100% yet whether or not It can be detected and to what extent? Would it look the same as if I were to clear the computer from a trouble code?? I also see a few tuners online saying theirs restore untraceable, is this confirmed or is it only speculated?
I'm about to pull the trigger on some longtubes and intake just getting jittery on it because of the tune..I can always throw stock bolt ons back on.
Thanks ahead of time for the input
