How to improve throttle response?

I am a serious lag when I smash the pedal. Each dealer (for the most part) has told me this is normal, but I don't necessarily buy it, and either way I can't stand it. It takes 1-3 seconds to gather and take off.

My truck is bone stock expect for a coolant filter and trans filter(will be installed this weekend). I do not have a fuel pressure gauge, and that is next on the list. With that said, what are the best ways to improve throttle response? I am seriuosly looking at the Air Dog II, and have just today discovered regulated return systems. Did anyone else deal with a similiar issue? Can you make it go away? Mods, tunes, etc?

Thanks for any help.

SCT tuner with custom tunes will make a huge difference in getting rid of lag. You will need guages. If I can help PM me..

I would agree with Cary. A custom tuned SCT will significantly improve your performance and help decrease your turbo lag considerably!

When you say FICM tune, do you mean flash? Or is that a custom tune?

I am not convinced my problem is the lag in turbo spooling, I am thinking it is something else. Just need to get a darn fuel pressure gauge and go from there I guess.

Most 6.0L I have driven do have turbo lag when you mat it off the line. They are designed to be rolled into the throttle. VGT doesnt know what to do when you floor it... But custom tunes will help greatly. I would recommend Matt at Gearhead.

I agree. Don't just mat it roll into the throttle and you'll get much better response. Tuning will help though.

I definitely get a better response rolling into it.

The only thing I can not get used to is being in traffic and trying to change lanes or using a short on ramp to the freeway, and not being able to get up to speed quickly. I do understand this thing is not near as nimble in and out of traffic as my old gasser, but sometimes it is just unavoidable, and I hate that sitting duck feeling until it takes off.

Mine is pretty much stock for now anyway and what seems to help me with upcoming onramps is to hit the tow/ hail button and that usually puts me into a higher rpm range for faster pick-up. At least it seems faster.

SCT, no studs...yet, Dual OEM intake air filter housings, Banks intercooler & intake elbow, Banks exhaust system, Windrunner ported intake manifold, Bullet Proof Diesel remote oil cooler & thermostat, AirDog2 (plus a couple spares), Power steering filter (Amsoil dual-bypass), MagTec deep ATF pan, Electric oil pre-lub pump, Dakota Digital gauges.
