Default anyone using the RC 75lb injectors?

Found these on the forced inductions website just wondering if anyone has tryed them yet? Finally an injector for big HP and still works with the factory pcm Maybe next someone will come out with a fix for our crappy MAF system.

I'm not planing to go much over 600rwhp so i'll most likely switch to the 60s myself but it's always nice to have the option to go to a bigger injector like the 75s if the need ever arises.

My friend Andy has been using these for months now. He made almost 800rwhp with these injectors, and an F1R on a C5R 427, and around 670rwhp on another car. He uses these and tunes them with great success..idle is perfect. I think they are perfect for FI on a big bore. The Mototron 60lbs are around 100% duty cycle at around 800rwhp. The 75lb Siemens are 85% both @65psi fuel pressure.
