Pittsburgh Power Kit for Twin Turbo Cat ??

Still wondering what is in the pp kit. Contact Mr. Haney or robsredford they are both pdi dealers. Neither will steer you wrong. Be shure to check all the basic simple stuff first, you can either search this forum about the basics ( topic has been completely covered on here) or ask them. Many things could lead to a sudden drop in mpg , and probably needs to be addressed before a tune. Imo.
