I just picked up a 1999 ex cab with the 5.9 magnum. It has definitely had some neglect but for 500 bucks, I couldn't pass it up. I have a modding addiction. The day I picked up my 2018 mustang gt I was ordering parts ...
So I've done a tune up, which helped dramatically. The rotor looked rough and there was definitely a few dead plugs. I've got a few other issues to fix still but I'm also trying to plan out my performance route. This will just be a truck, nothing fancy and occasionally tow a car trailer.
99% set on doing long tubes. The price difference between shorties and LTs is negligible and the LTs come with the Y pipe. I know shorties pick up torque faster, but the LTs seem to overcome that by 2500 by the dyno tests I've seen. My only concern is, will the factory harness reach the up stream 02 sensor?
I doubt I'll change intake manifolds, as I don't want to lose any torque. I may do a larger TB and possibly spacer if they actually help(still researching). The factory air box is in rough shape. The piece going to the fender is is rotting away and the filter box is falling apart as well. So I'll need a solution for that.
Next step would be tuning. I've only seen one recommended tuner on here. Is there others?
Next I want to clean up under the hood. Has anyone done an evap delete? I think I'll do away with the PCV and run a breather unless there's an issue besides fumes?
