Slow spool

I seem to have some acceleration issues.

As I accelerate, I notice the turbo doesnt really spool up until i hit 2000-2200 rpm. that seems kinda sluggish to me. i hear guys talk about how their trucks will spin the tires off...mine wont even chirp. when the turbo does spool up, the truck takes off like a scalded cat. what is the normal RPM in a early 99 7.3 where the turbo really spools up?

does anyone have any ideas? i am thinking of replacing the intercooler boots as they has alot of crud on them. i am assuming they are leaky. I am sure this is at least contributing to my problem...i am assuming they are stock, but i have only had the truck since August.

I have also had some minor trouble with that dang EBPV. It was opening and closing at highway speed. doesnt seem to be doing it now, though.

...or could the wastegate not be closing all the way?

what do you guys think?

(no gauges yet. the chief financial officer (wife) has not yet approved the request.) LOL

not only that if your not pushin enough fuel you wont make enough exaust and your turbo will spool real slow. but yeah i would definantly change that fuel filter and if that dont fix it get a fuel pressure gauge or take it to a mechanic so he can put his gauge on it. what kind of egt's you gettin?
hope the filters all it is tho.

What intake is on it. The stock early 99 air box is a piece of $#!+. The tabs break and allow dirt to enter unfiltered, also it sucks air from the inner fenderwell, so in the rain the filter looks like wet toilet paper and air won't flow through to well. Also if it has the original airbox I'd look at the turbo impeller to see if it looks damaged.
But on the otherhand on a stock truck with lift and big tires you'll have to powerbrake it pretty good to break em loose.

So basically your truck is stock other than the exhaust and lift/tires? When I put my old early 99 on stock it wouldn't do much of anything other than run like a turtle.....basically everything you described.
