I have an 88 GTU, with the following mods:

Cone filter
RB Road Race(True Dual) Exhaust
Removed rats nest (don't think this matters, but eh)
TB Mod
Currently wired open aux ports


Just wondering what most of you guys (with similar mods) tune you're SAFC2 to? I know, all cars are different..I'm just looking for a relative range to start from. I don't want to be leaning out by 2% and slowly taking it down more in an area I need -30% in..

 

you really want to get on the dyno for this, but for my (street ported) 88 GTU I actually had to richen the mixture up significantly-- ~6% throughout the powerband.

 

Richen? Wha? I was told to start at around 3000 and start leaning out from there.
