Just installed JB stage 1...questions
I just installed the JB stage 1 tune on my n55.
Does it actually adapt over time? From a rolling stop, I find it slow before I feel any surge of power. I had the same tune on my n55 335 and it just felt very different.
I and waiting for the stage 2 upgrade to arrive but was just curious.
