LS3 injectors on a LS1 I was given LS3 injectors for a 2010+ camaro, 52lbs/hr, I want to know how can i run this on my 98 camaro. just by looking at it i can tell the connecting mechanism (as in the clips) is different, but it looks like it has two different cables going to it like the LS1 injector.
Also what about tuning for these, can the 98 ecm run these injectors?
they are bosch btw
I also noticed that these are shorter than the stock ls1 injectors, does this means that i would have to modify the fuel rail mounts since it would be sitting lower?

i currently have a walbro pump from racetronix and i also have HP tuner VCM suite. i am aware that it has to be tuned. I am also aware of the wiring being different. I was told i need extensions for them, but do you think i can run without the extensions if i have LS3 fuel rails? do LS3 fuel rails mount the same on the intake manifold?

LS3 injectors are 42lb @ 58 psi
You need to chop out a portion of LS3 IFR table and interpolate it to fit your LS1 IFR;
you also need some of the other tables like the voltage adjustment and the small pulse adjust;
do you have tuning software (I have interpolated the tables), or will your tuner be doing this (he would already know this)...?
