I have a set of LT1 injectors that I want to swap into my car. Will I need to reprogram to make the best of the injectors? Will I have any driveability issues? I realize I may have to trim the injector pulsewidth down a little, but then again I could just go back to a lower FP setting, right?

 

I'm currently running them.


Look in my sig for a taste of my mods. I have burnt a number of proms trying to slim down the fuel, they run nice and rich.

 

So you're saying that they are going to be too much

Would I be better off going backwards and putting in 19lb.'ers?
They would technically have a better spray pattern at a higher pressure and run at a higher duty cycle.

If I can do this without creating other problems I will do it this weekend.

Thanks for the help....

Hey mike, I have not had any trouble running svo 24# on my car with the stock chip. But car was running very lean after the cam swap. Now my BLM's and FI are very close to 128. And I still get 20 mpg with the tops out and my foot in it.

They did not make my car any faster at WOT with the stock chip, but the car runs a lot nicer at part throttle.

I hope this helps
