we used the blue spring and no shims for the install. First we installed it to VTA but apparently my car didn't like it. It kept sputtering/stalling and the CEL would flash on and off. Weird!!! Although we didn't disconnect the battery but not sure how much good that would have done anyway. So we reconnected the recirc hose & so far so good. I really like the sound, I just wish it was as loud as it was in VTA. It still turns heads though, and I'm such a ricer that I can see myself upgrading to a different valve soon (probably Turbosmart since its the loudest LOL).
