Looking for Turbo Lag fix
I have a 2003 6.0, one of the very early engines.
I have gone through all the reflashes, a turbo replacement, and injector replacements. And everything has gone ok. Then about 1 year ago I took it in for an oil change and they reflashed the truck again. Now I notice less power (seems like my low end torque is gone) but it also has a bad turbo lag (very annoying when getting on the freeway).
I have asked the dealer, and they said everything checks out and there is nothing they can do. They say that is the latest flash and thats all they can put on it.
Now I am looking for a way to fix the problem myself. I do not want to spend a lot, nor do I want to make it into a drag racer. And I really dont want to do something that will cause more problems.
Any suggestions?
I am sure that this topic has already been discussed but the "Search" function on the forum does not work for me and after looking a hundreds of topics I gave up and started a new one.

I'm in the process of going with an aftermarket turbo, specifically the one I keep on looking at is the ATS Aurora 2000, since I'm really looking for more efficiency then insane amount of power(there is such a thing as too much, especially one you reach a certain point of how can you justify having all that power on a daily driver), I'm sticking with their smaller turbo. They do have a 3000 and 5000 turbos, difference being the size of the turbo, if you go to any of the bigger ones 2 things will be happening. 1. as they are bigger turbos you will be getting some lag back. 2. because they are more powerful turbos you will have to do other engine mods to accomodate that higher power. However, I think a tune and an aftermarket turbo are really going to be your best bet with getting rid of that lag.

I have been looking into the tuners.
They all seem very similar in the specs. I was thinking about getting the Superchips Flashpaq.
It says that is will do a lot of things for my engine, which all sound great (if there true). But it doesn't say anything about improving turbo lag.
Is there anyone out there with first hand experience with tuners helping the turbo lag?

I have a tuner and I still have the lag, if you want to get rid of it about the only thing that will do it is to go with a more efficient turbo that doesn't have the VV design on it.

Ask down in the competition section of the forum.
Hope this helps

We've got some anti-lag tunes that I have been working on for a while. Works best on the hotter race files but I'm pretty confident I could retrofit the parameters into any kind of calibration you want.
There are a few people here who can attest to the fact that its effective
Maxium4x4 was the first person here to run it; I'm sure he will throw his 2 cents in.
Give one of us a ring if you want more information, contact info is in my signature.
If you do want a non-VV turbo, I install S300 turbos from BDP which are very similar to the Aurora setups (only aren't nearly as expensive); but to be quite honest the gains will be more in midrange performance with the smaller-end compressors and won't really net much of a decrease in lag.

fuel=heat=spoolup=hp=egt can= parts.
Bottom line is more fuel=more heat=faster spool up=more HP and also=high egt that YOU MUST monitor and control with the right foot or a programer to defuel at high egt or parts will suffer .My edge platinum does all the above but mpg will drop.Something about a law of physics about something for nothing.
My previous truck was a 98 Dodge 12 valve Cummins it dynoed 400hp/1086 ft/lbs of torque on the ground.As much as I like my Ford with the Edge at the 115 hp level the ole Cummins would run off and leave it,and the more load on it the worse it would be.I'm sure I'll get hammered for that statement but I put 100,000 on the Dodge at this hp level pulling the same rv and goose neck trailers,so I know both trucks and I now work for Ford KTP so the truth does hurt.
Add fuel and enjoy.

If you want anti-lag just ask Matt....
I tested his creation for lag and I had a blast. hardint you need custom tuning to appreciate what can be done to the 6.0...your Cummins had more go fast parts available to make 400HP. The 6.0 can match 400 with a good file.

Maxium4x4,
Obviously you did not read the torque numbers, your Dunbar says 696.3,The poor little 5.9 twisted 1086,hook the trailers up and head up the hills and see where the 6.0 is then. My egt will get out of hand now and Working Where your truck was bilt,I'm very aware of how much fun your headed for when your head gasket lets go if thats all.
Like I said i've owned both and if I twist my 6.0 like I did the 5.9 I will kill it.As A side bar I have an 05 common rail Cummins setting in the shop for the Ford.

You do realize 400 HP is 400 HP once it's moving, right? Assuming that both are geared correctly to compliment their powerbands both trucks would maintain the same speed on the same grade with the same load. The torque will get the load moving faster through first gear, but after that the torque is of no real advantage because HP reflects the overall average torque applied at the wheels throughout the powerband, not peak.

The vast majority of tuned and un-tuned trucks never have cylinder head issues and to make a blanket statement such as you did is quite near-sighted and statistically very incorrect. There are plenty of members on this site tuned and most all will attest to having no cylinder head issues (or any other issues) even after modification- as a matter of fact, I think there have been a few polls taken on this very issue; search for them and take a look. I've broken one or two (
) of these engines myself and I know well what it takes to do so- for the average user the 6.0 is more than resilient enough for the average public.As a side note, what did it cost you to get that 12v to 400 rwhp? It costs 399.99 to do so on a 6.0....I'd be willing to bet I can fix the toasted heads on it several times for the same cost as it took in mods to get the Cummins there.

I will argue no more as I stated orginally I would get hammered for the statement. Bottom line is Have you owned both brands?Can you get over 1000 ft lbs out of a 6.0 on #2 and keep it together 100,000 miles and tow 14,000+ regular?

I have an 03 and have used every type of tuner good or bad right up to Dunbar's Dyno run with totally toasted heads. hardint No one is arguing with you, just pointing out the facts your not aware of.

I can tell you that your 399.99 cost is way off Matt. That in itself is not a true statement and very misleading.
here's the cost from start to finish(is it really ever)
SCT Complete diesel/gas tuning package $9000.00
Engine Analysis or CP testing equipment $20000.00 purchased so we can tune properly.
New truck for testing $45K+(our's not someone else's)
Air intake $400
Exhaust $400
Trans kit $3300
Studs $750 installation $500
egr delete cuz you can't get it to tune over 380hp without it gone.
fluidamper-$480?
Total for 400hp= almost 80k
The cost of a new engine from Ford is $15-20k everytime. It's not about making max power, it's about making higher safe power.
