Re: Headers switch to long tubes
yes you need to kick up the hego delay then use the histogram to dial it in
kick up the CL delay
kick up the o2 sensor duty cycle
then make sure you dont get any cross scavenging with the x. You can tell by the lambses going in far opposite directions while accelerating. If it does then disable hego 2. If it only does it on decel then use LOLOD / FN338 to force open loop on decel.
