I just want to let everyone know that I've been a newbie since October of 04 and I've been modding my car since. All mods have been simple and relatively beginners stuff. As I progress, I found that allot of my mods didn't work well with the Evo. My latest upgrade was with Works and I had them install the WRP Aperture II Throttle body, Go Fast BOV, and a P2 ecu flash. I'll I have to say is, " Thanks Works"! They really kick ***. They were tenacious with fixing all the issues that I have with turbo lag and any other problems existing. Their products and service is truly reliable. Most importantly, they test all products fully to ensure that you don't loose any drive ability with the Evo. So to make a long story short, I'm a newbie and modding your car is fun but if you want the full potential of your Evo and have it running properly, look for a tuners shop that knows their stuff, like Works.
