[QUOTE="AllanB, post: 429403, member: 3978"] You gotta deal right there. But I have got a few other things to do first. It might take 4 weeks or so before I am ready. But in the mean time if you find someone else that wants to take you up on that, don't wait on me. But thanks for the info and offer. I will sure take you up on that if you haven't gotten rid of them before I am ready. I will check on the other parts and see where I can get them. Unfortunatley they are also rpm dependent lol. I have seen that the 6.4ltr red lines 1000rpm less than my 6.0ltr. Also I might be wrong, but I am betting that the guys that write these tunes. Know exactly where the peak power is in our rpm range. and probably setting it to shift just after it passes peak power/rpm. I don't really know that, just a hunch. [/QUOTE]
