I also see now how my car's fueling was way off when I initially installed 30# SVO's in my car. I went from an old post on LS1.com that said a 30# SVO injector was equal to a 36.14# injector at LS1 fuel pressures.
From the above formula you can see that they are equal to a 34.64# injector. Explains why the dyno tune took a while.
A good lesson for everyone to take everything you read on the net with a grain of salt. The info could be wrong.
A better write up in the Help section of HP Tuners about this (injector swaps) would be nice.

i didnt feel like making a new post.. was wondering what is truely needed to swap in the ford injectors onto the rail. i've been searching for the past 2 hours without much luck...
do i need to change connector type? run a resistor? run a spacer on the rail?
i have a set of red top 30lb'ers and i have a 04 gto w/ ls1 thansk
