By those codes they hooked up the rear O2 sensors and NOT the fronts. Non functioning front O2 sensors will run like garbage when in closed loop, but should run fine in open loop. After a warm up try ...

Since you are a 2500 I'm going to assume you are running the HD 4l80e, which is a good thing. Being a 3/4 ton also means that you will have the larger 2-3/4" headpipes connecting the exhaust man ...

Thanks for the update.

1)How much did your cruise rpm increase?
2)Stock exhaust?
3) What kinda tire height are you running?

I wonder if this was a non-Direct IUnjection engine like in the GMT- ...
PostForum: GM Performance Forum   Posted: Thu May 31, 2018 6:03 pm   Subject: Boost referenced Fuel pressure regulator idea

Every vac referenced FPR should be rising rate, or rise 1 pound of fuel pressure for every pound of boost. It would be like driving your truck N/A down in an underground tunnel.

Hey Jim, I do know that some of the gear makers make thick and thin ring gears so that spacers are not required for the different breaks in ratios of some of the rearends. This is different than your ...

You also have to use the correct sensor be it the resonance style or flat response style.

I forgot about Kenne Belle as well, they originally used Autorotor compressors when they did the Ford Lightning 99-04 5.4 liter trucks.
In 2005 they introduced their own 2.1, 2.6, 2.8, 3.6 and 4.2L s ...
PostForum: GM Performance Forum   Posted: Thu Mar 08, 2018 2:58 pm   Subject: 04 2500HD 6.0 Tow rig Maggie or Whipple?

True but I was referring to relatively mass produced cars. If Whipple was the best, they would have gotten everything after the Ford GT. Probably not as fuel efficient as the TVS and/or more expensiv ...
PostForum: GM Performance Forum   Posted: Thu Mar 08, 2018 7:34 am   Subject: 04 2500HD 6.0 Tow rig Maggie or Whipple?

Eton is huge and they probably design and tested their superchargers in collaboration with Ford and Gm' R&D deps.
Pretty hard for Whipple (Lysholm) to compete .

Whipple did do the 2005 Ford G ...

Its pre programmed for the 2014+ LT-4 GEN 5 SBC engines. If you want to put a s/c LT4 engine into anything along with the 8 speed auto, it would work.
