6L tune up??
Hi guys,
my truck needs a solid tune-up and I keep seeing "6L tune-up" but have no idea what the term actually means and what it consists of. I got a 302 HO in my 90F250 so can this apply to my truck??
If someone can break down what is performed in a 6L tune up, that would be great.
I tried searching up on it, but the internal search engine for this site isnt always the greatest....
Thanks guys

You don't have to use the exact same parts as that, but its in the right direction. I had the MSD coil on my truck for quite a while and noticed nothing. I have a new Motorcraft one and it runs just as good as the MSD, mpg is the same too. I think it actually starts quicker with the stock coil.
Just make sure you get Motorcraft or Autolite plugs.

Thats pretty much what it is, but I suggest you just do a full tune up with Motorcraft wires cap rotor and coil. I had all that stuff on mine for quite some time and it did not change the fuel economy. I did a complete tune up with factory parts a little while back and it runs just as good.

I would say the point behind the 6L-Tune-up is simply doing the basics and ensuring you have a healthy ignition system. If, say that you just change plugs but the wires are 9 years old, it could have a small, yet fractional benefit. I have an MSD Blaster coil, Cap, rotor, with Motorcraft plugs and premium plug set. I noticed a bit of an increase, but yet, I also had MAJOR exhaust work done too. I had the heads redone, manifold, plenum cleaned. But it' hard to say just what if any it has helped. It feels like it, yet could it be psychological, yes and no.
Just keeping the truck running healthy is the heart of the 6L tune-up and when it runs well, in general the owner is a bit happier with the outcome.
Just my 2 cents.

May I also suggest a couple other fundamentals to go along with the ignition tune-up? Obviously, a new air filter is in order, but the fuel filter can make a big difference and is frequently overlooked. Also, the throttle bodies get dirty very quickly. Cleaning them with a TB safe cleaner can make a very noticeable improvement. Make sure to open the blades and clean both sides and as far back in the bores as you can get. I have even removed the TB to allow a thorough cleaning if it was really dirty. Also, while cleaning it, check to make sure the throttle blades open completely to the horizontal position. You should be able to see the edge of the blades and both sides of the throttle shaft. I found that the TB blades on my '97 5.8L lacked almost 10 degrees from being going completely "wide open". A slight tweak of the linkage stop flange with a Vise-grip fixed it.

I was saying that its in the right direction, because its a tune up. But yeah, I think it is unnecessary. I had no gains at all. I like running stock wires because they actually fit right. Also I feel the stock coil is just as good. I did some research a while back and there is not much different between the stock coil and MSD coil.

Yes I did read it, but i am a damn nuwbee if you didnt notice the name. I am new to this and find that everyone has a different take to things. So instead of coming to this thread to ask me if I read it, in the amount of words you have just written, you could've easily just wrote you thoughts on it.
