i am purchasing a 95 CTD 5 speed. the guy im getting it from says it is "chipped" for better fuel economy. his father put it in before he purchased the truck from him and is now passed away. ive been in the CTD department for a while now and know for shure there is no way i can think of to "chip" a mechanical inj. truck unless he slid the plate forward. thats what i think what are your suggestions/opinions???

 

You're right, a 12v can't be chipped. It's pretty easy to remove the fuel plate, esp. if someone's been in there before. Do a search and look at the pictures of the different plate profiles too see which plate you have. Just yesterday I removed a stock plate that had been moved full forward; it didn't provide much extra power, so if you're worried about wear and tear, I wouldn't be, esp. w/a 5spd.

DTR member "Dieselnick" is giving you good advice on that 95' Dodge CTD 12 valve you are purchasing. There is NO WAY to "chip" a 94'-98.5' Dodge CTD 12 valve engine. The word "chip" actually applies to the older Ford Power Stroke Diesels before they began using the "fueling modules or boxes" which they use now. Actually, even the 98.5'-2002' Dodge CTD 24 valve trucks and the newest 2003-2008 Dodge CTD CR Trucks NEVER used "chips" either, but the "fueling modules or boxes!" Also, you can use the ECM Programmers like the "Smarty", "Bullydog" or "Diablo" Units.

that is what i was thinking the guy may not know what he is talking about. i havent seen the truck in person yet but if he dont know what he is talking about maybe i can get him down on price! !)

Good point buddy!

I will research and give you some links to how to get more power out of the Cummins 5.9 12 valve engines found in those trucks. It is all done through the P-7100 Fuel Pump, specifically, by going into the AFC housing where the "fuel curve torque plate" or "cam plate" is located.

Here is one link for you that I had that will show you how power increases are done on the 94'-98.5' Cummins 5.9 12 valve engines:

http://www.tstproducts.com/pdffiles/INSTRUCT98.pdf

If that doesn't work, go to www.tstproducts.com and once there, look to the lower left section of the page and you will see a section titled: MORE INFO.

Below that, you will see a section titled: Installation Instructions.
Click on that and you will see the procedures for the 94'-98' 12 valve engines.

 

well i figured it out it is the plate because he failed to tell me about the "screw" that is shiny NOT black on the afc housing apparently the AFC housing has been tampered with

 

does TST offer a "power kit" for the 12 valve engine? or is that site info on how to get more power out of it? my powerchoke had a TST 6 position chip in it.

 

yea but the power kit is nothing electronic. its usually a fuel plate and a boost elbow.

 

If your looking to buy a fuel plate DDP has a kit on special for $100. It comes with a #8 (I think), a boost elbow and a 3K gov. spring. The #8 would give you about 230 HP 605 TQ in stock position (all the way back).

Nick

 

No, you got me all excited. That is an AFC spring which controls low boost situations, it has nothing to do with how high you engine will rev. A stock spring will only allow so much travel so that is why companies have softer springs to finer tune your truck where you want it.

 

ok ive seen the #8 plate but what im wondering is what kinda power you can expect with the #10 compared to the #8?

Here is a breakdown for you on the power ratings for some of the other "TST"
Fuel Curve Torque Plates:

Auto Transmission Trucks:
-------------------------------------------------Power---------Torque---
1.) #10 TST Plate--------------------------------300 H.P.-------700 ft.lbs.
2.) #8 TST Plate---------------------------------230 H.P.-------605 ft.lbs.-
3.) #6 TST Plate---------------------------------250 H.P.-------635 ft.lbs.-
4.) #5 TST Plate---------------------------------280 H.P.-------675 ft.lbs.-

Manual Transmission Trucks:

1.) #12 TST Plate-------------------------------230 H.P.---------605 ft.lb.
2.) #11 TST Plate-------------------------------280 H.P.---------685 ft.lb.
3.) #10 TST Plate-------------------------------330 H.P.---------750 ft.lb.

Other manafacturers of these cam plates rate them differently, so there will be some "variation" on the H.P./TQ. ratings. FWIW, a #10 plate in either an auto tranny truck or a manual is pretty hot and I highly recommend aftermarket trannies or clutches if you go that route. Also, EGT's will be pretty high with it!

so if i went with the #8 i should be fine on stock repaced clutch?? or according to your chart i would want the manual #12??

 

------------------------------------------------------------------------
I would start with the "MANUAL TRANNY" #12 plate to start off with. Mark Chapple at "TST Products" used to have an "exchange" program for the plates, that being, if you didn't have enough power with one he would let you "trade-up" from say the #12 to a #11.
