Is there any chips made for the 97 cummins 12v? Ive only found 98 1/2 and up. how hard is it to get about
500hp and 1000 ftlb's ?

97 and back have the mechanical Bosch P7100 injection pump, not the crappy prown-to-fail VP44 elec. pump.

They take different fuel plates to increase fueling, not electronic chip's.

Do a search on "12 Valve" happy reading, you'll be doing it for a while! :bigthumb:

Vp44s rock! Yeah right :roll: . Go to http://www.dieseltruckresource.com . They are a ton of forums to look at. 12 valves are easy to bomb and are waaaaaaaaaaay less expensive compared to a 24V.

Some of them use a mechanical version of the VP44...I believe it was the VE44...and it is suseptable to the same things the VP44 are...the only difference is that the mechanical lift pump tends not to fail like the electric versions do.

And the 12 valve mechanicals are 1989 through 1998.5 . And as stated by these guys, no chips...everything is mechanical...no computer control on the engine.

I had to read this a couple times to figure out what you are trying to say. The 89-93 CTD use a VE injection pump. It is a rotary or distributor style injection pump. It is nothing like the electronic VP-44 except for the fact that both are a rotary style pump. The P7100 is an inline pump, and they came on CTD's from 94 to mid 98. 98.5 to 2002 have the VP44 and are electronic.

On the P-pump like your 97, you can slide the plate, change the plate, grind the plate. Whatever you are comfortable with. You can also change the injectors for better/more fueling. A word of caution is, get some gauges, boost and pyro. Run the truck a while to get a base line then start tweaking. It is very easy to put the fuel to these engines, but you need to watch the pyro to make sure you don't have a big ball of melted aluminium.

As Got Smoke said there are no chips but there are fuel plates. A good place to start is here http://www.tstproducts.com/index.asp?PageAction=VIEWPROD&ProdID=119

As for making power the P pump is king but you will be looking at some other mods then just a fuel plate.
