Secondary Butterfly Valves...Needed?
I am having my UIM coated with ceramics and one shop won't remove the secondary valves for me and another will remove them but does not usually replace them after coating. I have read these are in place to help with cold running and to prevent backfiring when throttle is let off too fast. I want my car to run like new but with more power. Could these valves and dashpot be removed without problems?
Thanks

Well the throttle body is here with me. I only sent them the UIM which has the secondary throttle valves on it. The place doing the coating is a rotary shop and the guy said they remove them all the time for customers. I was just curious how many people had removed them and if I should expect any starting/ driving changes due to removing them.
