The largest gain in HP came from the Predator with built in sport tune for my chevrolet SS. After Having installed Magnaflow Catback system and K&N cold air induction. The predator made it come alive. I have not seen much increase in gas mpg but it is not worse and have more HP, torgue, and rpm's. Trnsmission feels more possitive on shifts.
