Catted or catless? On stock tune? (Well technically have jb+ if that even counts lol)
I know catted would be a safer bet due to cel, but alot more costly than catless by a huge amount.
I did get an email response from one of their reps mentioning it shaves off anywhere from 0.1-0.5 seconds off 0-60 and 1/4, 60-130 depends on several factors. Who knows.
