Im about ready to head up to Riverdale and visit Browns Diesel to get my Goerend transmission and smarty. I know i will need a fuel system upgrade but will i be able to get away with doing it right away. The truck has only 5000 miles so its still new. I will be getting the airdog 150 but if i dont have to do it right away i would like to save up alittle and wait. Also i have a stage 3 dr. performance preditor should i keep this with the smarty or just get rid of it. Thanks guys.
