ok, my 2.9" zzp pulley and lucas #42's are here. i want to put the injectors in right now... is that ok? i know they are easy as hell to do but will i be running to pig rich? how bad would it be if i ran i like that, or even put the pulley on as well....?
*note one of the moderators was running a 3.0" pulley on stock injectors, and stock tune
and since this is a returnless fuel system with no pressure regulator, how is it that the ecu isn't just gonna put in the same amount of gas as stock?

 

um. car will run like doo doo... eco controls inj pulse width to control fuel, nothing to do with fuel pres, that remains a constant.. all a 3" pulley does is increase boost sooner but the stock computer bleeds that off @6000 rpm withou the reflash.

 

is there anyway to manually lower the fuel pressure on these cars?

 

nope, unless you make it a return style fuel system with an adjustable regulator (which is in the works by the way) but thats about it.

 

ok.. thats not what i wanted to hear. but thanks.. i guess i just have to wait for the tune time rally

 

we might be doing a dyno and tune day at RIPP in SI soon if your interested
