okay yeah i figured ide need a tune, im planning on getting one after everythings on. i know a guy who does a good tune on these and charges like 200. and ive heard bad things about the zzp box tunes. any thoughts on which route? and yes ive lowered my car and got that bad vibration so as a hurried solution i ordered the shortened dogbones but kept the regular ones just in case i needed them later. what kind of issues are you talking about them causing? and nobody makes like block hugger headers or anything that anybody knows of? its fine headers are a little ways off. im doing all my modding very slowly over time starting with all the supporting mods i can come up with.
