That's one of the problems I'm having
Upgrades and stuff for the F22 seem to be very few and very far between. Besides a turbo kit or an engine swap, there doesn't seem to be too many big boosts that can be done. Little things here and there, but not a whole lot.
Most sites talk about the H22 or the ITR's. If anyone has some sites with idea's/suggestions for the F22, please let me know.
