Will I need new tunes?

[PHS79]

I might be swapping trucks with my dad, he would be taking my 04 F150 FX4 and I would get his 02 F350 7.3L. My parents bought a motorhome so they will no longer need the F350 for towing their 5th wheel, so I will up grade to a diesel to tow our TT.

Currently my dads F350 is only running a Gryphon with 25hp, 60hp, and 80hp tunes. Otherwise the truck is bone stock, performance wise. I am looking to install an intake (thinking either Tymar or S&B), a turbo back 4" exhaust and maybe a 203* T-stat.

With these mods would I have to get new tunes or would it be fine running the current ones?

Thanks for the help!
