hks vein pressure converter help!

[mitsu-luver]

Ok tomorrow i might be picking up a hks vpc. but i got kinda confused because when i go on the hks site i see that some of the chips for them are vehicle specific? so how do i know that this will work? he says that its programed for 660cc injectors and that it doesn't matter what year it should still work? is that true? please help guys

As long as the adapter harness is the correct one than it should work, I assume you have a set of 650cc injectors or maybe he has a 450cc chip so you can use the stock one's.
