hi i am almost in the process of buying headers...choosing either spoon or mugen headers..but i am not running any aftermarket ecu like spoon or mugen ecu etc..my mods i am running so far are.. street tuned apex vafc, spoon air filter, spoon cf airduct, t1r exhaust, t1r testpipe, t1r grounding kit, t1r voltage stabilizer...wondering if the header will be a good combo with this setup and help me in hp gains...anyone experienced using i/e/h without using aftermarket ecu and just a properly tuned vafc and got gains? if do so approximately how much and any dyno plots?
