What color is your GTR? I've seen a red one and a grey one around the Bmore area before, not sure if either was yours. I'll fill you in on the tune after I get it, and let you know how NGP was. And yes, Aberdeen is a bit north of Bmore. I've read of a good number of people that did Stage 1 right away without any engine break in. The engine definitely does break in though, I could tell a big difference came around the 1500 mile mark for me. Warms up faster, and I'm getting 35+mpg on the highway now instead of the 31-32 I was getting before it was broken in. So waiting 1,000 miles or so would be your call.
