I have a chip that looks like the one on RPM's website but they have told me it is not theirs. In addition to the one on the site mine has a ribbon cable that goes to a remote mount selector with a display. There is a sticker that has V5-50# printed on it. It appears to ba a piggyback style but I am not sure. I have installed 50# injectors and a 3 bar map. I was told by prevous owner that the chip was programmed for the 3 bar and injectors. He gave all of it to me with the sale of the truck. I am new to the TY community and the lingo about computer tuning is greek to me. I am not new to the S-series, just new to the Typhoon. If anyone can give me some insight as to what chip I have and some installation instructions regarding orientation on the pins that would be great.
