Ok so i have a civic si with k&n short ram intake, dc sports headers, and invida q300 exhaust. I have some insane engine lag going on and it happens in every gear. If im in 4th gear going 35 and try to step on it a little bit the rpms will rise but i wont get any acceleration. Now the only way it runs fine is if i start off fast and keep the rpms high. And it will go all the way up to redline if i let it but just wont go anywhere. Help please!
