if your going to upgrade I suggest you consider all factors

 

i know it is, but why would i need a HP fuel pump with the ko4 if no one else runs one.. or am i missing something and im wrong. what if i just lowed the fuel presure to 3 bar and out in the new injectors..

 

my appols I thought you upgraded the injectors??

 

no not yet, the program im running calls for a AFPR set to 5 bars and stock injecotrs, the pc-16 calls for 310cc injecotrs and an AFPR set to 3 bars, so i was going to just put in my injecotrs now lower the APFR let it run rich (rich being better then lean) and see if that helps, then when everything is working well go pc-16

 

when you do then consider this - fuel air ratio and delivery ( one cant do without the other ) in equal formats, I could go even further but you guys only bolt on performance, very sad

 

have you ever tried to **** through the eye of a needle, just an example

 

of course you don't your not a tech but I really do know what I'm talking about
