Alright then a 100 dollar stainless dp an a 36 dollar aluminized cat delete pipe will be next if I don't just get the whole stainless system
Go-ahead - spring for the 3" down pipe and the 4" straight. Make it Santa's early stop LOL

I found my Diamond Eye Stainless for under 300 - install was easy - and it fit like it was suppose to be there.

Could be a little louder though! ;-)

I got to hear mine today - uhhhh

Ok gentle readers, if one should find oneself with AB injectors in his rebuilt 97 - that I am thinking was a single shot system, I got to see it run today, BIG LOPE - could be smoothed bringing the idle up 2-300 rpm them let it down - engine straightens up - They tell me it likes to die if you let off the throttle and put the clutch in.

The shop filled out the engine build sheet and specified AB injectors - he INSISTS AB's are single not split shot - EVERYBODY here says otherwise.

Shop says they sent the ECU out and had it re-flashed - I don't know wither the specs were 1997 P/S or AB injectors - will investigate that tomorrow.

I have read some CPS can cause a lope in the idle - I ordered the dk blue Ford one to replace the light grey one on the engine now - it's worth a shot,,,,,, It will be here tomorrow. Hopefully.

If I understand correctly - the truck will probably run best with AA injectors and the proper ECU - better mileage etc. - I'm afraid the shop will opt to re-flash for Cali emissions and cut the mileage and figure the customer will never know.

I'm reluctant to go tune crazy with out EGT and Boost gauges - at least.

How do I get this ironed?
figuring I'm about tapped fron this ordeal......

The Federal trucks came with AA or AO singleshots, same injector more or less. The early 94.5-95s seem to have the AOs. The ABs are the 120cc California splitshots for sure, thats what came in my 97 Calif.

In addition, the 96 California PCMs were DPC-202s but with splitshot tuning, so the Federal DPC-202 PCM is a direct plug-in into a 96 California to run singleshots. The California DPC 202s do not have the glow plug current sensing like the 97 Californias do. The 96 California auto PCMs are MIF-0 through -7. The glow plug current sensing California auto PCMs are MME-0 through -7 and are DPC-312s, very rare birds to find since no longer available from the dealer. To switch to a Federal OBS PCM, theres about 20 wires to swap around.

Never knew about the non glow plug sensing 96 California DPC 202s until my buddy showed up with one.

Also, the 17* hpop will support 160 stageII splitshots to 408hp, I did it using a stock muffler on a DynoJet 248 without load cell. The 17* held 2800psi at WOT. An improved HPOP will give better results though. It did when I changed HPOPs and tuned for 3200psi with terminator twins.

Well, first week with the new motor in the 97 OBS w/AB injectors.

Truck runs EXCELLENT. Starts easy, idles well, pulls like a big dog. - In a good way.
Low temps have been around 10 deg. - I'll plug her in at least 3 hrs. No issues. I had 1 start lil below zero with no block heater - started well and idled, - no throttle for a few minutes.

We replaced the ICM and PCM, PCM was factory 1997 5-spd and I replaced the grey CPS with a Motorcraft - not sure which one fixed the dying and rough idle, the modules were throwing trouble codes. I'll swap the CPS back when it gets warmer.

The truck is getting about 16 MPG around town and limited highway and I'm in and out of the throttle frequently for break-in.

Rebuilders used aftermarket thermostat that is not working - that changes today.

Ill update if right temps change things noticeably.

I just put ADs in my truck with 1 AE and I'm getting a really awful noise out of nowhere. I can only get the truck to run with the 10k mod as well. Without the 10k, it fires then dies instantly or will start with the throttle all the way down and not go above idle. I'll figure out how to link a video of the noise in a second.

I would get a scanner on it and see what the ICP and IPR% are doing. Are the ICP connector pins in good shape and making good contact? a lot of times the 10k mod can mess up the connection when removed. Are you running programming for the splitshots? Is there a chip on this truck? Maybe check the chip connection. Cheers!

I have not gotten tunes done yet, but I read and was told that splits would work fine with single tunes. I will check the pins on the ICP, I bet that's what's going on in regards to starting. What could the sound be though, it one shows up when the truck is idling in park or neutral.
