Jim, I think your issue is going to be a roll cage. What are your EGTS with the new pump at 3600+RPM in 3rd and 4th?
It's not that fast! I'm not looking to get that fast as my pockets aren't that deep. On the EGT's, they are livable and no my 2000 degree gauge is not pegged, there is some left in it on the pump, actually quite a bit, but I really like the way it drives and I don't want to loose that. Cruise is a little touchy but it was before (need to limit the vacuum to it) driving around is fine but I'm use to the light throttle needed, idles weird! More like a hum than a diesel chop... . nice balance job. I'm going to make a shift point change as it really likes RPM, Not a pump for the faint at heart! heck I haven't even tuned it yet, just pulled it out and stuck it on... not bad changing the pump either!
Nowell, this pump is not a gift from Piers for the PDR racing group but I would not have it if it wern't for them as they got my old pump sold for me, unbelievable they way they treated me! Now it's up to me not to let them down and knock out some numbers.
I think it's sick when you get to this point of the power scale and if your not breaking stuff or putting the truck in the ditch it needs more. If I go past were I'm at it will happen and I will loose some driveablity! I like being able to drive to the track, set it up, run then drive back home without changing injectors or other stuff like that, suspension changes are no big deal and that I can live with.
Jim
