Has anyone had perf. problems when using SLPs siamese intake runners? I have a 92 350 Z with a Paxton SC. Last year I was able to run 12.7 @ 108 mph with 1.7 60 ft times. This year after installing the runners I can't get below a 13.3 @ 105 mph with a 2.0 60 ft time. I had the same problem when I ran NA but I also had a bad spark plug wire. I'm going to check the ign. system but am looking for any similar stories before I switch back to the factory runners. Thanks in advance.
