Sometimes mine will start real crisp where is shoots right up to 900 rpm and sometimes it just goes up to 500-600 slower. Is this normal?

 

i get crisp starts but gotta goose it alittle to ildle out, not much but just a little, rpms never shoot up

 

With all the problems you've been posting about your 6.0L it sounds like your tune is wiggity wack. Post up your HPT file and let me look at it. I bet your running air flow is too low. Ever play with your RAF table?

 

This isn't a problem. It's just something I've noticed. I think it also did like this with the 4.8L, but I can't remember for sure.

P.S. switch on over to that Vinci 062 cam so I can know if that's the one for me

 

Not until I dyno my truck this Friday, I have an appointment setup to get you guys some numbers and graphs

 

try and get your dyno operator to start off the pulls as low as possible so we can see what kind of power you are making down low

 

Oh trust me, I will. Guys who post those 3500+ pulls give no important info whatsoever. I have a 5 speed so I will start as low as the dyno will allows. Ideally I would like to start at 1500RPM

 

On my dyno, the guy started the pull at 2500, but there is a spike abnormality for about 500 rpms before the accurate info shows up. I'm gonna try and ask him to start it lower next time.
