Hi 2 all. I have a 4x4 Sirion 2004 1,3l 102ps. I have installed a free flow air filter and the apexi safc2.Yesterday I went to the dyno to tune the safc2.I adjusted only the hi-throttle and made adjustments that vary from -10% to -20% at specific rpm's.I got very good results (power reached 110ps) but I don't know if these setting are safe or can cause damage to the motor. During the adjustments I managed to keep the air-to-fuel ratio below 13:1. Any help??
