Throttle Body Spacer Dyno Sheets? Does anyone have any dyno numbers before and after on the Throttle Body spacer? I don't want to deal with the annoying noise if it isn't going to do anything, I just happen to have one laying around that matches the engine...came off my Chevy Colorado which shares the bolt pattern with the Trailblazer, which, from what I'm reading, is the same as the LS4. SO, any dyno numbers on these? I may run to the machine shop and get those stupid grooves cut out since all I really need in plenum volume.
