All the above advice is correct an great info.
I remember the first vehicle I had, spent every $$$ I had to get it and hoped the previous owner left enough fuel in it for me to get it home!
So there are a few things you should check to protect your new “investment”, before you go fast.
“First things first though, and I'm surprised no one said this yet,”
BRAKES!
Make sure your are in correct working order.
Never trust that the PO (Previous Owner) that you bought it from with
YOUR and your
LOVED ONES lives!
If you haven't done a brake job before, or been taught how,
find a professional. Either a place that specializes in 3/4 to 1 ton work trucks or some place that has a continuous business with larger professional work trucks.
Go to a place where their customers rely on their vehicles to put food on the table.
Chances of getting a bum deal will be reduced, compared to some of these “assembly line” shops.
Also surprised no one mentioned first to check for the dreaded KDP!
Do a search for “KDP” on the forums and do it
now!
The cost to repair the aftermath, will feel like buying your truck a second time.
Then hook up a pyro gauge, and a tach.
Many instructions are here on the forum as to how, where to put the sensor, and where it should be reading.
Then you should find out where a Dyno Day is being held.
This will give you a baseline to work from.
Depending on you graph, your milage and other factors.
You can have someone knowledgeable tell you if your vehicle is running at its best, in it’s current state of tune.
You might find you need your valves adjusted, your injectors are plugged up, your pump might be getting tired.
Get it running right, first.
Then if something needs to be replaced, you can always justify getting the “better” part to replace the wore out one.
Remember, it only costs 100% more to go first class!
And listen to the old guys.
They’ve already spent their children's inheritance, and broken a bunch of parts finding out how not to do it.
Why would you want to repeat their “experiments”. :-laf
You’ll have a lot of fun for a long time to come.
I’ve already got over 300,000 on mine... ... .
