Well the thing is... recently my motor was sounding like crap till I adjusted the valves. I got the stock performance back ,and I don't know too many people who have their own tools who know how to work on a K-series motor and do the valves right. My homie had the same problem after he got Hondata and he thought that he got ripped off for $500. now that's a lot of money. Now how would you feel if you went out the pockets 5c's deep and your car still felt like crap? Well anyway we made an audio recording of the engine bay sound at 750 rpms in both motors and you couldn't hear anything out of my car. but all you could hear from his motor was really loud ticking. So I adjusted the valves for him and now he has 14's on lock and he's going for low 14 high 13 on a quarter after the ES MM and the torque damper is put in. I mean you guys can be scheptics if you want, but all I know is I offer my services while the EP next to me sounds like a time bomb. So suit yourself, it doesn't hurt me any, I'm just trying to help out.
