Hi guys Im looking to get a bit more power out of my a3, its a naturally aspirated 1.6L petrol producing 102BHP, engine code AVU. Im not expecting big gains due to the lack of a turbo and it being my first car so a remap just wouldn't be feasible, I'd be expecting a 10% ish increase in performance from either a box or tune which would take me between 110-120BHP. The problem is I cant find a reputable box for my engine, only cheaper ebay ones. So my question is would there be an increased risk to my cars health using one of these boxes or not as I assume they are all essentially doing the same thing, does anyone have experience with these? Or does anyone recommend any brands which cater to my engine? Thanks everyone!
