Why the 01 version, the 02 version was the one recommended by Allen over the 01 version in my 4x4. I saw a 41 rwhp gain in mine with a 93 octane tune (I had a 93 tune with the stock cam also).

I think Allen has my shift points set to 6200, I'll have to look at my file and see, I have the LS6 springs but I dont know how high is too high, my hp peaks at 5800.
