i just purchased an 05 passat with 191k on it all stock. i have a back ground of working for several diesel shops working on diesel pickups but im a rookie at the vw diesels. im wanting to get the best economy i cant. so far i have two fill ups of 37 mpg. not bad compaired to what im used to driving. but im sure i can do several things to help fuel milage. i plan on cutting the cat and muffler out of it and putting a twister muffler on it to keep it from droning. i was also thinking of deleting the egr and cooler. i know it helps in the bigger motors but not sure if it does in these little tdi motors and if it requires a programmer to do it. any help would be greatly appreciated.
