12V VE hear.
what mods were/ are on the 97 you swapped your 93 ford for, or did you find one of the hens teeth unmolested (stocker)?

wrap or blanket the manifold, turbo, and down pipeto get better lower spool dyno proven you tub video manifold blanket test. the only thing under your hood that likes heat is the hot side of the turbo keep it inside the hot side everything eles will thank you.
as oilpan said a better turbo that is small enough to still spool at 55 . the s360 SXE is what i want to get for my truck but with a small housing unless your going to pump it up over 400hp the 12cm is big enough

is the toy hauler going to be a bumper pull or 5th? it changes our suggestions. one of the design aspects of my Aero Tonto is to be the airfoil / diverter for a 5th or bumper pull.
when towing you will probably notice the biggest advantage of the 1st gen 3:1 TQ :HP Vs 2:1
thoe heavier than the 1st gen the 2nd gen is a better truck .
lock up torque converter, heeps better aero than my stack of bricks ,



( oilpan the CAC was always there. 89-91 was Water Jacket CAC located in the intake manifold, 91.5-93 was Air to Air CAC in front of the radiator. nonIC is slang {only twins can have an IC} like Posi in a chevy{ posi is a tm chrysler product})
