I have found a wonderfull deal in a 2001 F-450 crew cab Lariat. It only has 48k on it and is super slick. Ive been running a 1999 V-10 since new, and this is my first powerstroke since the old 7.3 non-turbo. I see all the new tuners out and which is the best for my 7.3. Itll be used for a welding truck and the total wieght of the rig will be about 14.5 to 15k lbs. I want all the horses I can get but am worried about exhaust gas temp getting to high. I have a superchips in my V-10 and it worked great. Thanks for any info. Also is there any querks with this year of powerstroke? Thanks again for any help.......Jamie
