So i have been trying to get the most out of my engine, and improve my acceleration so i can at least show up these civics around here and not lag at stoplights. But still not quite were i wanna be. I have these mods as of now, obx cold air with aem dry flow filter, jba shorty header ( i know a svt will get more power but wanna keep car carb legal), greddy ti c exhaust setup with 2 inch piping all the way back and no resonator ( 2 inch is just a little bigger than stock), obx tbs (just for the whistle i got it cheap so didnt consider it a waste of cash), cfm silicone spark wires with brand new denso iridium plugs. What can i do to the engine to help my acceleration and get more power other than changing out pistons, and boring my block, or adding a turbo? anything cost effective is a plus as i dont make too much cash. lmk, and would a tune make a difference? if so where can i get one and how much on average do they cost? I also have ran fuel system cleaners, and cleaned my maf which helped restore a little more power but not a lot.
