I am running a ported s16g turbo a mkiv i/c with a 2g maf (without honeycombs) 560's a walbro 255 (rewired) and my fp set at 38psi and my low settings on my safc are:
1k +8
2k +12
3k +14
4k +14
4.5k +16
5k +16
6k +16
7k +16
My fuel trims are L=100 M=102 H=109
Does anyone else with similar mods have to add so much fuel?? I am only running around 13psi for the winter. I just changed my o2 sensor last week and I don't have any boost leaks. My gas mileage is about 14mpg. I also run 93 octane. Also my hi settings go from -4 up to about +5 even at this low boost setting. . I am able to tune for 20psi and zero knock in the summer but i end up with my high settings somewhere between +13 to +19
I am not a newbie so please post useful info
thanks
