I love my truck, but probably wouldn't get the EB again. I do the wrong kind of driving to really reap any benefits from the engine--99% short trips in a very hilly terrain.

 

EB Screw, 3.55 gears, 4x2, 7700 miles... No, I would not pay the extra $750 for serious turbo lag, the extra complexity of twin turbos, and disappointing gas mileage if I had it to do all over again. The 5.0 is way too close in mpg and performance for what i'm going to use it for: hauling the family and the dogs to the beach or getting groceries.

 

serious turbo lag, I dont think you know what your talking about. Go drive another vehicle like a diesel with a turbo and youll experience lag.

 

Why would you say a man does not know what his truck is doing? I suspect he does. The EB I drove when making my decision had a lag everytime you got on it. That was a big part of my buying decision.

 

Yes I would. Only wish the turbo's weren't so muffled. I'd like to hear more hiss... (are you reading this Ford engineers). I've never had a problem with turbo lag. Even when you get the dip who tries to cut you off ( you see the car late next to you and they're already on the gas trying to cut you off)I've had plenty of boost to keep them beside me or more often get ahead of them.

 

No turbo lag here either.

 

It's not turbo lag. Some of the ECM codes have more delay programmed in than others. People think it's turbo lag because there's a delay in power and this engine had turbos. My 5.4L truck had some level of throttle lag too. The lag in power is identical on both motors. There wasn't a turbo on the 5.4L so what was causing the delay?

OP, if my truck was totaled today I'd look for one just like it tomorrow.

 

It may not have been turbo lag, but that is what the salesman riding with me called it, so that is what I have called it. His comment was that I would get used to it, and indicated it was on all of them. I have since learned from members here that some have it, some don't. Possibly a reflash could eliminate it, don't know.

 

Thank you!!! Every truck has lag during acceleration. Drive a diesel you will find out what lag is.

 

Because there isnt such a thing. Notice I didnt argue his other comments as if thats what he thought than fine. But there is no turbo lag in a EB. There is acceleration lag but dang near every vehicle has that. Slam down on your 5.0 once you will not get instant power no vehicle does specially with an auto tranny unless you are at a complete stop.

 

I just crossed 1000 miles so i'm not too experienced as far as the truck goes BUT, i love it. Getting great gas mpg and the power is soooo nice...

 

I would buy it again in a heartbeat. The only hesitation I've had is when I go from cruising on the road to full throttle very quickly. It seems to hesitate for about .25 seconds. It's kind of like when someone pokes you with a stick unexpectedly. You first reaction is "what the heck'" then you respond. I have found that if you don't slam it to the floor and push the pedal down a bit slower it goes faster much quicker. I don't think it's turbo lag, because the engine doesn't do anything then it goes. I think it is the ECM getting overloaded and trying to catch up, which is why it doesn't happen when you press the throttle slowly.

 

I’m fairly certain the delay and slight lag when you really romp on it is ECM tuning done to protect the rest of the driveline. The motor is fully capable of making 400 ft-lb at 2000RPM. That shows the turbos are making lots of boost early in the powerband. Look at the cars such as the Mitsi EVOs which are well known for really bad turbo lag, they do not make much power down low and gobs of power up top. A turbo is nothing more than an exhaust gas driven pump. If there is not enough exhaust flow it will not spin the compressor wheel fast enough to make the boost levels needed. The EB turbos are small for a reason, they will make boost soon and instantly. The problem is unleashing that much power on the rest of the driveline instantly. The shock loading on the components will lead to increased wear and breakage. To limit this, the ECM can be programmed to dump boost, retard timing, lean the mixture and back off on cam timing for a slight bit to lengthen the time the power increase is applied. This gets rid of the shock loading and the problems it causes. The other N/A motors in the F-150 lineup do not generate the instant power levels the EB can. I’m sure Ford has some power limiting applied to limit driveline shock as they have done this for years but the amount will not be near what is required for the EB.

 

Ok, lets put it this way. In the EB when I went to get on the freeway, and merge with heavy traffic, I punched the accelerator and nothing happened for a count of 1-2 and then it took off. That was repeated everytime I punched it to pass on the freeway. I am alive enough to know when there is a delay in response, whatever you wish to call it. My 5.0 does not have that. I punch it and it goes and I better be prepared to cut the wheels if there is anything in front of me as it responds and accelerates much quicker than my 5.4 did. If there is any delay in it, I really do not care as I can not feel it. I have done a lot of competitive drag racing over the years and I know when an engine is responding and when it is not. You don't want to call it lag, I kind of like the term myself. regardless, I did not like the feel of it whether it was caused by the turbos or something else. The salesman siad it was, so I assumed he knew what he spoke of.

 

^^^^ The what ????

Anyone ever see the graph depicting pedal position versus actual throttle opening versus rpm/load? It's by design. The PCM is filtering yer inputs, to preserve the drivetrain.
