Powerdyne Programming

[Dan96z71]

Just wondering if I would still need to run my boost-a-pump if I got a customer tune that is built for a L31 with a Powerdyne on it.

Thanks,
Dan

Give us some more details on the truck and what you&#39;re trying to accomplish.

Right now I just want to get it running as good as possible. Future mods I would like to swap in a LS1 or 6.0.

I was just wondering if I have a good tune would that call for the right amount of fuel without using the boost-a-pump.

you will still need the boost-a-pump to provide enough fuel.

I believe the setup you have has an FMU, right? Or is it a boost a pump that increases voltage to the stock fuel pump? These terms are always interchanged and I just want to be sure I know what your truck has.
If so, that will definitely help keep the a/f ratio rich during boost.
We&#39;ve tuned quite a few obs truck with chargers and we remove the fmu, install an inline pump and tune for timing and a/f ratio, it works.
However, I would only suggest 5psi max. on the stock fuel setup with the inline pump. The fmu may give more potential, but I&#39;ve always thought the fmu&#39;s were a patch.

Does your setup come with or have an intercooler? If not, that will dramatically increase performance&#33;

Sorry for not answering the correct answers before. I guess I didn&#39;t know exactly how much detail you needed.

No, I do not have an FMU.

I have a Hobb switch that is "supposed" to switch on when you hit something like 3PSI and that will then turn the boost-a-pump on.

Boost-a-pump adds extra voltage to the stock fuel pump.

I have never changed the pulley on the powerdyne, so I am not pushing that much for boost.

So do you think it would be better to use an inline fuel pump or continue to use the boost-a-pump?

I don&#39;t have an intercooler on this setup and I am not looking to get massive numbers out of it. I just want it to run nicely.
