Performance upgrade questions

Right now I'm running a late 99 with a k&n air intake and 3.5" straight pipe.

I'm thinking about putting in a WW2 and stage 1 injectors off of the tony wild man website with the tony wild man tunes.

1. First question is why are the injectors so much cheaper on the TW website? They are full force injectors. What's the difference between single and split shot?

2. Will I need a new fuel pump?

3. Will I need a new HPOP

4. Is there any transmission upgrades I can do to my tranny to make it a little stronger

5. Are these 3 upgrades good choices? I'm not looking for a drag truck I want a truck with good mileage and good reliability but the extra power is nice

99 f350 7.3 4 door auto trans, 6637 intake, 4" exhaust, 6 blade compressor wheel, gearhead custom tunes, adrenaline hpop

Cant answer reliability of injectors sold thru him , sure someone else will chime in.
Singles flow a bit more and are supposed to offer better MPG's. require custom tuning to run. I have not seen the said MPG increase with singles.
Your fuel pump and HPOP are both fine , the singles actually require a bit less oil than the splits. Your Mods don't require either unless one is just weak.
Put a John Wood Valve Body in the tranny at a minimum , upgrade to a 6.0 cooler.
Get at least an EGT and Boost gauge to monitor that new power.
I think you'll be happy , cant vouch for TW tunes but lots see to like them.

you probably need to check with them to see what size injectors they are - the stage 1 , 2 and so on can be pretty misleading from one vendor to the next - get a CC size and nozzle size , it removes all doubts as to what you have.

Sold 01 350 6" on 37's and mild mods, 00 X 4" on 35's, 02 f350 4" 35's modded from fan to drive shaft, ridin the 03 with nose conversion with 125k and counting upwards slowly.
Never had CNC's poo on any of it, never will.
