Going from 28lb to 42lb injectors

[MathiasBlum]

Hi all,

Can anybody guide me regards the injector flow rate. I need it changed when I switch out the stock injectors with som bigger from TSP 42lb injectors.

I tried to read the help in the editor but cant get the injector "Tool" to work?

Somebody?

You need the injector data from TSP. They should give you that. If they haven't email them with your ecu model po1/p59 etc... And see if they can send it to you.

The data that is input to the ecu is dependant on the injectors tested fuel pressure and what pressure you are going to running.
The other data factor is whether or not you will be running a boost referenced regulator or not.

So, what pressure do you intend to run?
Did you install a boost referenced 1:1 regulator?
If you don't and picked a stock return style LS filter then it is set at 58 psi non refrenced.
