hi there,
i had a dyno run done on my car yesterday.
the tuner told me he was going to change the timing a little to raise my power.
(R33 gt25t: stock ecu, stock turbo, turbo back exhaust, 12psi, fmic, pod.)
the car initially only pulled out around 150kw's and then after playing with timing it brought it up to 191.3kw's
i was advised that the car would cough/hiccup at idle due to that change in timing.. and it does every couple of seconds - which i dont like.
what i wanted to ask though is if this was safe ? my car feels faster but i dont want to push it if the timing advance poses a danger to my engine.
Any advice would be greatly appreciated
