Sup guys, i got the sct xcal2 sf and installed it on my 01 gt by selecting the car and octane (93) mainly. right now i cant advance the timing but some guys at sct might fix that. my question is how much should i advance it? they said the 93 octance tune already on it is advanced +4 degrees. should i advance it more. i find out tomarrow how much end user adjustability i will have. whats your guys opionions to how much timing advance should i do to the 93 octane tune built in it.

Bump

you can bump it up a little bit at a time, and listen for detonation under accell.

it shouldnt be a problem, just dont increase it a ton at once,

and ALWAYS run 93 or higher
