I could be wrong on that, but I know of a couple people running about the same boost, on LT4s, moving toward 7000, so, for now, I'm leaving it there. I'll swap springs when I replace the lifters in the future, and rethink it then. I don't have traction anyways, so there's no point in beating the car up, lol.

I have to agree with you there. Since completing the build I find myself driving the car more and enjoying every minute. Previously I was shifting lower than now around 58-62000rpm. So in a way I did change my SP but was wondering if it would benefit at a higher range.
