My trucks almsot complete with the GDP fuel system twins and headstuds. Will i have to run crazy larry for the twins, or can i set it low for every day driving and not hurt it? Since i dont have injectors or a cp3 is their limit of how little fuel i can pump to it?

Bump, i guess to simplify it will it be safe to run on the economy setting with the twins and stock injectors, or does it need more?

morkable

only one way to find out for sure,, try it out,, wont hurt it anyway,, but man,, I run everything full out,, just modulate the skinny pedal, that way its allways there,, and it dosent hurt driveability

Acook, the advantage of twins is that they will run like stock virtually with no additional fueling.....but you will only be utilizing the top turbo. First you have to find at what psi your big turbo starts to light. I have three boost gauges so I know exactly when the biggin lites. Since I ported the head, the biggin **** on at about 17psi instead of about 23 before. My wastegate was opening at 22psi but the volume of air and pressure must be opening it a little sooner now. Morkable is just about right. If you want to fully use your twins you will need the fueling set high and limit the fuel with the go pedal. I run on Smarty 1 and TST 1 virtually all the time but this is probably 450/1000. If I need more than this, then I should be on the track. My Water/meth is on all the time now....it comes on at 19psi boost which is now perfect with how the twins are spooling. ks
