OMG!
tons of power with the Patrick G tune behind it.
if you are considering, I have another thread about the spring seats. they are bigger than a stock set like what comes on the Livernois Stage 1 DoD kit.
In my opinion, these are awesome in power delivery.
I greeted the PRC owner at Birmingham International Raceway in Steele, Alabama. Really nice guy.
they are expensive but pound for pound, they are worth it.
