Although the HOM feature was originally intended to be activated by race fuel on Stage 3 SRT-4s, there are two ways to activate HOM on pump gas. As far as I know, I'm the only one in the area who uses the two different options so I can turn my race gas mode on with pump gas. I do use race fuel when competing though since it's more reliable. When I ran Collins and ZUL8r's buddy with the RB26 S13, I was on pump but had HOM on.
