Just finished cutting the groove. Cut through on one side and have now made repairs on it with JB Quick. I will finish the job on friday, have to work, and finish the Idle Air Bypass rerouting as well. I will also post a picture of the finished mod and provide a followup on the results as soon as possible. other repairs also have to be made but should be finished by the end of next week. This vehicle was getting 20.5 to 21 MPG before the MOD.
