Slight Hesitation when trying to pull out fast.

Ok so maybe I expect to much of my truck but I'm just curious if this can be eliminated with a better turbo or ficm tune or anything for that matter. Question is I am having a small issue let's say I'm behind a bus that has stopped here in the city and want to pull out from behind and take the opportunity to slide in a gap of cars moving in the left lane to me, I have to floor it practically and even then it moves a bit then small pause then takes off Bam! sort of a hesitation. (It's always done it) And other than that once it takes off its amazing how it pulls .Again this is starting from a stand still. Are these trucks just like that can anything be done for it to take off quicker?
Is it just the time it takes for the turbo to spool up?

Yup turbo lag... its not a gasser no instant HP...

A tune may help, but you will never lose the lag.

you can move the lag all around, bigger turbo is more lag... compounds are less lag... you can change out wheels, etc

I run an atlas 40 and a PHP DD80 and the lag is much much better but its never gone.

Everything with a turbo from bikes, to diesels will have a lag.

I have looney tune and once it takes off its terrific just terrible for in the city (not the tune but that slight lag). I have thought about the ficm tune but i wonder if it's that much better . What's php dd80?
Also I was reading this post and mine also leaves a black cloud of smoke

you'll learn to drive "around" the lag. rolling into the throttle is a good way to avoid a big pause in power.

keep in mind you're not driving a little honda car either. these things are pretty heavy and take a little bit to get going.

QT's economy tune is pretty good at managing turbo lag, you may give that a shot.
