G20 Van with RV Cam no power on acceleration, where to start?

[Raymo86]

Thanks, I appreciate the information.

I have been adjusting the VE, but I did not adjust the AE tables (or turn them off), which could be part of my issues. I have been using this tutorial from EagleMark (excellent stuff!!)when I run the BLM calculator, and update, I think the PE is adding fuel, which is leaning out my BLM data, as the numbers are getting leaner after using the calculator. http://www.gearhead-efi.com/Fuel-Inj...data-Tutorial!

Can a stock pump get more that 13 PSI? Do you recommend updating the pump and the Spring? I will play some more with the VE tables tonight, but am not against upgrading the pump and spring, as they are both orginal as far as I can tell.
