I've ordered my parts for my stage 1. SE Heavy Breather, ThunderHeader slip-on (keeping stock header set up for now), and TFI (Gen 3). Should have all my parts in next week so I'll let you all know how it goes. Thanks to the forum for all the good help, information and advice. I've really enjoyed speaking with the Dobeck Performance staff. I made the mistake of not doing my research and got talked into buying the FuelPak. After studying your notes on TFI I cancelled my order for the FuelPak (got penalized $50 restocking fee) but took it as a lesson learned and feel I will be much better off with the TFI. Hopefully I will have good news to post later next week. Thanks again HDTalking staff for your help.
