Okay, so I did my initial fuse pull and reinserted after only 4 hours. Unfortunately, we can only get 90 here unless we want to mix with 104 - that will come later. After the car warmed up to temperature, I noticed that the idle had smoothed out to where it was hardly noticeable at all. As to power increase... I can honestly say the car was more responsive and felt like it shifted better. The power seemed to come quicker - if that makes any sense. I can definitely say there was a positive difference in my LS3 after the pull.

P.S.: A black GT500 came up to me later and gave me a couple of revs, but I wasn't biting...
P.P.S.: Also had a couple of APD 4x4s behind me all the way to Beluga point. Might be because of the plate...
