HELP -mods for 98 Super Duty ?????
O.K. guys I have done the searches and looked around but I can't seem to find all my answers. So maybe you can help me out.
I own a 99 Super Duty built 7/98 , can't say where it came from but its got a cat on an automatic tranny so I'm expecting California. Most of my work has gone into the exterior of the truck (shell, rack, 05 headlights, etc). The only mod I have done to the engine is Autometer gauges (trans, pyro, boost) and 4" Magnaflow exhaust (cat back).
I have heard the first version SD suffered from a bad intake system and wonder if I should address this first. I am also wondering if I should kill the kitty and add the Magnaflow turbo back tailpiece and tie into the new stuff in the back. I have had a hard time finding info about the differences in the first couple of years of the super duties but along with everything there are usually improvements to be made. I just don't know where to start !!!
I am mainly looking for improved gas mileage and lower EGT's but like us all I do occasionally like to step on it. This is my work truck and gets driven
So that do you folks think I should start with ??????
AND THANKS !!!!!!
