I didn't want to be the first one
to say bs as I remember what people said about my car after porting the inj and plenum comming out to 409.9. but I will have to agree with Ullys' take on this. NFW. bad dyno or motor work heads-inj-plenum porting by previous owner. but whatever if he loves his z thats what counts. we all are hopeleely addicted to the KOTH. on that we can all agree!!!!!!!!!!!!!!!!!!!!!!!
