whats done to my truck?

[JMoore17]

first of all hello, new to the page. i buy and sell cars for a living and came accross an 03 4X4 6.0 that i took a huge risk on. the info said it didnt run and i hopped in it and hit the key and the key didnt even ding (battery completely dead) so i was thinking if this goes for extra cheap ill risk it. (you're not allowed to mess with the cars before you buy them) in the end i was the high bidder and i threw two car batteries in it (also it hasn't ran or been plugged in in 3 months and its the middle of winter) cranked it over and it fired and cut off 3 times in a row, 4th one fired and stayed runnin but ran a little rough, after about 30 seconds it sounded awesome. pumped up the flat tires and drove it home. that was on friday now tuesday ive been driving it literally everyday (after checking fluids) and i swear who ever had this truck had to of done upgrades because its just too fast (sideways all the way down the street when the posi kicks in) anyways im going to check to see if the muffler/cats are deleted and going to measure the diameter, what else should i check? thanks.

You're probably hearing the OEM 03 turbo with an open exhaust

If its whistling like that then its got a straight piped exhaust. 03's are known to whistle insanely loud with a straight pipe because they have a 10 blade turbine wheel in the turbo and the later 6.0's have 13 blade wheels so they don't whistle as much. You should check to see if it has head studs and/or an EGR delete. If it has those two then you might have struck gold depending on how cheap you bought the truck for. You can sell it for a good bit more if its studded and deleted. It sounds like it has a programmer of some sort already on it or you wouldn't be able to get it sideways. These trucks are bad slow with stock tuning. If you can't figure out what's done to it then post up a pic of the engine bay.

First pic I'm holding a factory head bolt, to the left is a ARP stud/nut.



Next pic is the tubing of a aftermarket EGR delete, yellow "X". Located on pass side between the valve cover and turbo.




Factory EGR cooler might be welded shut, only way to tell is to remove up-pipe and stick finger in EGR cooler to feel welded plug.

No real way of telling if the truck has been tuned without pulling the heads to look at the spray pattern, you can look at the firewall behind the parking brake, some programmers require a hole drilled thru the rubber oval grommet to pass wires thru, but so do gauges. You can also check on the exhaust manifolds for a EGT probe, and also look on the down pipe. Some programmers "piggyback" into the PCM/harness, the PCM is behind the driver side battery, tucked under the fender. You may find the programmer bolted in this area.

If you stomp on the pedal from a dead stop, does the exhaust tip dump out black smoke. A stock tuned truck won't blow black smoke unless there is a damages CAC/exhaust system.


You could post lots of pics of the engine, I'm sure we can tell you what we see.

i almost dont wanna say how much i paid for it because its so ridiculous but i dont care, the bid got up to $1750 but after all the taxes and fees it was $2400 even. the thing about it was me and this guy were bidding and i was like this is it (at 1650) and he bid to 1700 and i was thinkin nah he can have it but for some reason i went again at 1750 (thank you god) and that was my LAST bid and no one out bid me, and i only beat on it about 4-5 times and like 3 times it was one wheel peel. then when i got on a nice straight road i boosted up came off the brakes some started spinnin and floored it. needless to say it felt like i was on ice, pics coming

btw keep in mind this truck is no where near in perfect condition, the passenger side window was busted out (before i got a new one) and one side of the bed is completely smashed in (priced one at $300) besides that theres a ding or two on every single panel of the truck

$2400!?! Crew cab or extended cab? I'll give you your money back on it haha
