Compucar LT1 plate kit?

Anyone using it or know someone who is? How do you like it and what kind of gains can I expect?

i use this kit,it adjustable up to 150shot,i used 125 jets on my lt1 when it was stock never have had problem yet with kit.used it for 2yrs so far.

Im not a huge fan of compucar, cheap selanoids, not a area you really want to skimp around on
