Not air sensor this will have no effect at all, CTS, this tells the ECU info on the coolant temperature and hence can fuel accordinly these are basically thermisters as is the ACT and they go out of range after a while provides false info. The CO needs to be set to what the author has written that chip for. If you do not know it is normally written on the chip itself, same applies for FP. It is very rare to need to adjust this though as most chips use standard fuel pressure (3.5 BAR).
