I will be using 25 lb injectors. My elevation would probley allow oem 19s but I will upgrade.
On my 1995 Eagle Talon tsi, my oem injectors don't max out at 15 psi boost and 6500 rpm. I have even hit 21 psi briefly with only 65% duty cycle on those injectors. Elevation is a funny animal.
Most oem injectors would max out at 1/2 that down below 5000 feet. Since I am at 8000 ft it takes more to max them out.
For instance this KB kit is a 6 psi system. At my elevation the first 3 psi just brings me to sea level. Apples to apples this KB kit for me is a 3 psi equivalent system. Below 6000 rpm oem injectors would probably work. Not taking that chance though.
