RACEPAK

hello everybody.

as i been told in the apexi safc i should set the sensor type to in:06 out:06
at cruise and with no massive load it reacts fine, but when i wot it and when i'm changing gears fast it responds slow (and boogs when i shift gears)

when i set it to in:05 out:06 it cruise like crap and boogs but when i wot it responds very well and spool faster.

what could it be?

ps.
450cc dsm.


thanks
