I'll trade you. LOL

My "SS3500 Yank" stalls to almost 4k. Its enough to get me 5mpg at best around town.

 

with your stock cam, when your foots on the brake, how high could u get your rpms to before launching?

 

Well I could only stall it up to about 2500 before the tires spin and that is still an issue. I have a set of m/t etstreets on the way. Do you guys think that I need to do soem exhaust work for the cam to opperate properly also?

 

You need to sell the Hyper and get that beast on dyno and get a real tune. Here is my dyno graph of what I picked up after I put the LT's and off-road Y on.

 

ok well the update is no it doesnt have any where near as much power as it used to. Now if you just floor it, it will spin to about 4k then stop. I used a tech 2 and seems to have 7 degrees of KR. But that wouldnt make that much of a diffrence would it?

 

you need the 02 pcm and tune for sure.

 

would that make that much of a diffrence? I mean It felt more powerfull before the cam swap. I thought I would feel at least a little more power no matter what after the cam was in?

 

it probably would it would take care of the kr and i geuss it has better tables in it and you need to tune for the cam anyway. that way it can use its full potential

 

Well I'm going to order my tunners some time or another when ever I get a chance. But why would the truck be slower now that the cam is in?

 

KR pulls timing and I bet you are running very rich which also hurts HP. Without a tune you will never see its full potential.
