I am experiencing both the throttle hang and moosing problem and am considering using the copper pipe fix. I have a 200 SVT and have heard there is a loss of power associated with this fix. Can anyone advise how severe the loss of power is and how noticable it is during daily driving. The throttle hang has not been too bad and the moosing seems to only occur during cold weather, so if the power loss ifs significant I may decide to just deal with these without the fix. Thanks
