I feel it is not needed this configuration will put out 531 rwhp and 643 rwtq at 16# of boost
read pro stock pony article in mm&ff last 2 issues that is why i have it installed on my car also
it should be one ground and the + to positive side of coil
you should check out a wiring diagram for your year car and get a few more opinions first :nice:
Is this the one for sale in the classifieds with the junk title :shrug:
those heads will hold boost unless they are warped then it will blow gaskets
use cometic mls head gaskets
check timing also
