newbie here, looking for a little insight

[chevysblow]

Hello all,
Just signed up for the forums today, been a ford guy forever. It all started hunting out of my dads early bronco, I now own 2 early broncos, and a 2wd
f150. But I dont want to bore you guys with that silly GASOLINE stuff. Today I drove home my newest member of the family, a 2001 F350 4 door long bed with a fabtech lift and the 7.3 and 61k miles.

Im hoping I can pick the forum brains abit, first off the truck has a 4" exhaust system and what looks like a stage 2 intake. I will admit I am a little new to the diesel side of fords, I have done some research before purchasing the truck but feels like i have barely scratched the surface.

I test drove a couple of stock trucks before this one and there is deffinitely a differance in the way the truck pulls in comparison to the stock ones. I have been pretty gentle on it thus far but have gotten on it a bit a couple times and it def blows some smoke and pulls hard.

My question is if someone hooked up a downloader and changed the settings would a performance diesel shop be able to hook up to it and tell where in the spectrum the settings are at? Can you only get so much performance out of a downloader before having to go to an onboard tuner/moniter? Really what im looking for is a fuel milage increase for DD and a tow/haul mode, along with probably a tranny shift change to hopefully help it last a little longer.

And lastly, I have checked the forums quite abit about this question and it seems to be talked about alot but differing answers. When letting off the throttle there is from what I can tell compressor stall? I have heard some people describe a noise when letting off the throttle and many people say its completely normal and others say it can cause damage to the turbo from the wheel stopping to fast from excess pressure backflowing and releasing. The stock trucks I drove I did not notice this condition on, is this condition more prone to pop up the higher the performance gets?Any reply would be greatly appreciated.

Sorry for the long post, but thank you very much in advance for any insight you may have.

First off, welcome brother!

Second, there are a few reasons it could be pulling harder. It could have different gears, the lower miles, its been very well taken care of, or its tuned already. Usually the 7.3's have a chip installed which is hard to miss.

No, if a shop hooks up to the PCM they won't be able to tell. Only if you send the PCM out to a tuner will you know if its been tuned. But if there is a chip plugged in, you'll know it.

Your talking about the turbo bark. Does it sound like this? truck :: 101_0451.flv video by exfoxfrk08 - Photobucket If it's similair to that, then that truck has had the wicked wheel installed on it and its nothing to worry about. Its the slower air hitting the exhaust turbine. No big deal bud. Stock super duty's without the wicked wheel will not do that.

Let me know what else you need.

Thanks for the warm welcome guys. I watched the video and it sounds alot like that although not as loud. I have not really gotten into the pedal yet still getting a feel of the truck, so im not sure yet whether or not it gets louder the further into the pedal I go. I was thinking of taking it to a shop so they could go for a test drive with me just to get there opinion, I bought the 7.3 because ive heard so many good things about them, and my overall goal is to have it last as long as possible, so I guess longevity rather than all out performance is number 1 priority. Thanks again for the info.
