I am trying to look for a possible tune for my truck. Call me stupid but ive been looking all over the place for a good tune for the truck but have had no luck.. If you have any recommendations please by all means shoot them my way. It is a 1990 Dodge D250LE with a 12v Cummins non intercooled

 

What are you trying to accomplish?......Ben

 

Nate, First Welcome to the forum ... that said, these are mechanical trucks not comp controlled, if you want more HP you have to turn wrenches to accomplish this, they are not plug and play ....that's the reason first gen owners love their trucks. Go to the sticky's at the top of the page and read, read, read.
Almost any question you have about these trucks is covered there or do a search in the first gen section .. for instance type brakes there will be several pages come up. Hope this helps ... oh ya if you decide to turn up your pump the first thing you need to do is install gauges ...pyro is mandatory and boost and fuel pressure is highly recommended.

 

There is no ECM in a '90 cummins truck to tune.
You can't tune something up that doesn't exist.
Like nonrev said, time to do some reading up on 1st gens. This site is a great place to get that reading in.

 

ok... wheres the hidden camera??!! come on its in that fake palm tree over there right?

as stated... ya can't just plug in a chip to tune a real engine it requires more skill than the new stuff first year for OBDII computer was 1996 everything before that ya need a wrench

 

I've got a tuner I'll sell you...


Sorry couldn't resist.

 

I also like the tuner that is called the "10MM", used along side of the tuner you pictured.
When "stacked" together they seem to really get the fuel delivery rate up.

 

Now that's frigging hilarious!!!

 

I hear this "10mm" tune is easily lost so extras should be purchased.

 

Fortunately they are universally marketed in a wide range of price and quality at a variety of suppliers from Harbor freight to SnapOn......Ben

 

True. I have learned that some engines are actually black holes for tools. My wife’s ‘96 Camry Wagon sucked up a Craftsman 10mm combo wrench in 2015. My Jeep KJ absorbed a Craftsman 13mm socket last winter. I’d rather offer up cheapos but I don’t have any. Even though I’m not OCD this causes me great duress because I like my collections to match and then have to search for matching replacements.

Fortunately with our old trucks, most tools trickle down and eventually hit the ground due to the open engine bays. That’s great if you’re on concrete or maybe even gravel but not in a field. I’ve also discovered that some species of grass/weeds can actually dissolve metal and rather quickly too. Some tools are immune but many bolts, nuts and washers are not, especially lock washers.
