found out the hard way the the Siemens Deka 46.5# injectors are way too big for my application. I purchased them from a LS1GT0 board member under the auspices that they were 46.5#. Being that my rwhp is in the neighborhood of 425-450, I need to trade with someone for a set of LS7 injectors. But I wanted make certain that knowone else made the same mistake and share the following information:

Gents there is a new "direct fit" SD (Siemens Deka) injector for LS2/LS7 vehicles, and the beast flows pretty damn good too good! At 54# that is approx. 12# more than the LS7 injector. This should supply enough fuel on a supercharged GM application to at least 625 to 650 rwhp Actual, and probably 675 to 700 rwhp on a turbocharged GM application.
Here is some info on them:
