Fuel Trims after S2 Cam install
After my cam install my fuel trims were way off. I am able to get my LTFT Lo to 0.4% which is good. However my Mids are at -12.5% all the time. Does this mean I need to increase latency in the 11.72-14.06 range or decrease it? Will doing that then affect my Lo?
I have FIC 950s and used the numbers provided in the super merge thread. On stock cams it worked out fine but with the S2 neither are really helping.

What would be the disadvantage of leaving LTFT on?
Personally I would try to rescale the injectors (injector size as well as latency) to get things back in line and then if needs be put idle into open loop and set the AFRs where required to get a smooth idle (probably 13.x afr).

S2s and idle on MAF in an VIII definitely prefer rich for the smoothest idle.
