Cleaning the shop today! Lots of performance parts!

Is the power plate good for an all stock engine. I’d it a ATR or RJC plate? If so can some one chime in on what the differences between the two if any other than the MFG. thanks

Go to rjc's website. They have data on what the plate does for you. The more I look at it the more I think it is an rjc. It looks very close to theirs. This was on my car when I bought it 7 years ago, hence my uncertainty in the brand.
