Turbo lag

Hey guys, I was wondering if anyone has suggestions for decreasing the "off the line" turbo lag in a 2006 6.0 with stock turbo.

put a supercharger on it instead.. literally.. But the lag is the way it is nature of the beast with a turbo... I am spoiled with the vgt on a 6.0 as if you think the 6.0 has lag?? you feel a dodge etc etc..

The 6.0s lag really isn't all that bad. Drive a 7.3 or a cummins and you'll experience some real lag. As for making it a bit better off the line I would get a FICM Tune. Look on FICMRepair.com and it explains it all really well. A 4" free flowing exhaust will eliminate any back pressure and also help a little. Custom tuning can change some parameters and help as well.

Do a little more reading on here and you'll find a wealth of knowledge on the subject. If you really wan to take off the line try practicing a brake stand. It's not exactly good for your drivetrain but the truck will take off a lot faster. Or if your desperate for a super quick jump off the line try a boosted 4x4 launch. On a tuned truck you'll be thrown back into your seat! The truck will take off like a bullet.

If you're referring to everyday driving and getting rolling from a stop light or sign it's the nature of a stock truck, if it's a race thing then you have several more options, 1.0 build boost with braking, 2.0.......
Hybrid Turbo
ARP Studs
Tune and FICM Tune
Monitor SCT ScanGauge Etc.

Do the above and you're only complaint will be tires are going bald.

FICM tune will make the truck drive like a gasser off the line.. night and day difference for me using atlas 40 or atlas 80.

Next on my list is a hybrid from the MAD scientist above lol

Thanks for the help. I am just looking for better performance in everyday driving. Can somebody please tell me how/where to tune the FICM? What exactly does the new FICM tune change to make the turbo lag go away?

Injector pulse width is changed for better performance especially on the low end. I'm using the Atlas 40 and it's great for my combo.

FICM Repair.com - Your Source for FICM Repair has all the info you need for the ficm location and how to remove. They have a big FAQ page that will probably answer any questions you come up with. I should be getting mine back from them this week with the Atlas 40 tune.
