Hesitation on EL Long tube headers
Hey guys I'm currently running a Nameless Long Tube EL headers with off the shelf OFT stage 2+ tune. Def getting more power top end but getting Hesitation/ flat spot on 3-4k rpm. It's pretty noticeable slow on that range and as soon as it goes over 4k dramatic change in power. any tune changes i can make on this issue? like valve timing or fueling etc..?

Torque dip absolutely still present with the Nameless header without custom tuning. Even with custom tuning it is weak in the midrange compared with an ACE or JDL. You can tweak the AVCS to improve it a bit but it is still going to be meh till 4k, then it wakes up.

If you do feel inclined to adjust your AVCS you can use these settings that have already been worked out.
