i managed 384bhp with a spacer , it will aid better airflow as it wentr from a 11.5 afr to 12.8 topend so that shows a restriction has removed slightly (i think the rest is in the elbow) any way i a logged egts on a 4 channel datalogger and afrs and the egts were safely even across the board , which is what they are in standard form lol , as mentioned above get a small turbo inlet
