yes mine takes a while too. look into the blue spring update. that increased my throttle response a little bit. the biggest thing to help that is an exhaust, and custom tuned SCT

Typical turbo delay?
Say your at a stop light and you stomp on the the gas pedal to the floor, what do you think the average delay is on these stock turbos. I think my seems delayed more than usually. I know thats a broad statement. I would think these stock turbos would only have a 2 second delay at most. Mine seems to be about 3 seconds. I know it may not seem like much of a difference but another whole second is alot of time. Especially when i am up agaisnt a chevy, lol. But seriously i am concerned that my turbo takes too long to spool and deliver

tats the turbo lag. since ur on 3 seconds, tats still highly debatable if u have a serious prob or not.
normally, it should be about 1 to 2 second delay. maybe u could do some maintenance stuff like, checking ur ficm voltage to determine if it's going bad, pull out ur egr valve to clean it, pull out ur turbo to clean it as well (now tats a PITA!), etc etc.
the other guys will chime in wif their wisdom and experience. i hope i've at least got u tinking and pulling in the right direction.

blue spring upgrade is good. if she's stock, u might wan to look into upgrading the stc fittings, dummy plug upgrades, and changing out the standpipes as well. u can do all tat. u jus need a lot of patience.
i've been there and done tat. phew! i get tired jus describing all this info. mercy me!

I have checked the ficm and its above perfect. I was just reading some info about these trucks and apparently the recoews say that they have great turbo response which mine does if im driving done the highway and hit the gas to the floor. But it does seem the "turbo lag" os just a little more than normal. Anyways i a. Appericating everyones responses. I am mechanically inclined. So if anybody has any tips that dont involve a bunch of dollars im game. Any procedures that you can post would be great too i do plan on cleaning the turbo soon on a weekend since i mostly do in town driving.

What is this "blue spring" update that you speak of? How is it done? Procedures? Average cost? Thanks.

pmoney1983, since ur gonna be pulling the intake apart to get the turbo out, u might wanna consider pulling the cac boots & tube out on the passenger side and clean wif carb cleaner. apparently, ford does not recommend using brake cleaner on most of their internals. dun ask me why. wat i read.
if u need torque settings, holler again. i'm sure someone will post them. if not, when i get back on later, i shall post them.

blue spring update is an update for came out with for the fuel pressure regulator. there is a spring that controls the fp. the stock spring used was on the low side of the spectrum(under 45psi kills injectors and over 75psi pops o rings) and when the spring would get old, it would get weaker, so the fp would drop below 45psi under WOT. the blue spring raises it to the perfect spot.i think around 62psi at idle rather than 56psi with stock spring. made a difference in throttle respose with mine. can get it from ford or IH, cheaper from IH though. anwhere from $30-$50. easy install. goes in the side of the secondary fuel bowl.

The PCM limits the amount of boost the turbo can build when you nail the skinny pedal to the floor like that. If you want it to take off like a streak of lighting...roll into the throttle. I wouldn't say feed it slowly, but don't just "dump the fuel" to the truck....sort of like driving a gear-grinder. Takes a little getting used to...to find the sweet spot on the accelerator.
Before you pull that turbo out...check to see if your getting under/overboost codes. If not, take it for a cruise where you get to make a couple of wide-open throttle passes. That will clear out the carbon & gunk around the vanes. Once a month will do wonders to a truck that doesn't drag trailers down the highway all the time.

do you have a boost guage? or a scanguage 2? to see if it is a concern or not the only thing you can really check is the boost it is putting out, if the vanes are sticking then it could create more of a delay than it should, but without a way to see the boost it is putting out and in what conditions it would be hard to know if the turbo vanes are sticking causing increased lag time. i think it was a horrible oversight to not place boost gauges on a vgt truck, but they got it right on the 05 MY's, cause it is about the only stock guage that is dead nuts accurate

Yes, don't floor it. Roll into the throttle and you'll get way better results. I hate getting wailed by little old ladies in k-cars...I've never tried tunes yet, but I'm sure the guys that write the tunes could over ride the factory programming that causes this.

From the numbers your posting...your turbo is working fine. If you want to pull & clean the turbo...go ahead. But I think your wasting your time. Though 32 psi is getting a little on the high side for a non-studded truck.

What do u mean its on the high side of a " non studded" truck? Also the turbo only hit 32 psi a few times with the trailer hitched up. Thats what it maxed out at. It would usually stay between 20 to 28 psi depending on the highway i would be on
