With a Pre charged set at 11.5flb with HN FTT will be over the top with a heaver pellet . The problem is the police do not test guns with a standard weight pellet. so your gun can be legal but fail when tested by the police depending what they are using on that particular day.
yes it can but they usually test first with the pellets you are found with and should take a diffent view if they are doing 11.5ftlbs and a super heavy pellet does 12.01ft lbs
than if they test your pellets and get 18ft lbs
yes both guns are technically FAC but the cops arnt quite as daft as we all think and think a good lawyer would be able to argue that you have taken REASONABLE steps to run a non FAC gun so doubtful the CPS would pursue it. tho the cops would still try and intimidate you into taking a caution and removing the gun for disposal
the 18ft lbs is go straight to jail do not pass go etc.
manufactures these days are so paranoid that guns come out at even as low as 10ft lbs on normal pellets and fitted with anti tamper screws
for FT i used to run my 177 Anshutz Comp gun at a couple of FPS under and we had to shoot chrono lane on the shoot i would set it with an allen key on the practice range chrono and when about to go home drop it to 10ft lbs again for travel
i also drive at 69 on the motor way not 50
