mp8 + auto transmission?
i am driving my 07 cummins 5.9 like a granny trying to get better fuel mileage, before i changed my driving habbits i was only seeing about 14.5 to 15 mpg. i was seeing around 20 with my 03, 6 speed. i didnt think they made that much of a difference but in any difference im thinking about getting the mp8 because i heard that they help alot but i dont want to ruin my transmission with extra power. i want to keep it going as long as possible. everything is stock with the exception of straight piped, and cold air intake. is there anyone else that is using the mp8 with a stock auto? and if so how is the transmission handling it?
