hi guys im new on here so please forgive me if i do anything wrong.

i have a discovery 2 td5 facelift 2003 with offroad goodies td5 inside stage 2 remap with bigger ally inter cooler and similar mods.

recently my top coolant hose was pressuring so i did the headgasket and problem solved :)

now i have another issue. it starts and idles a treat. i havent heard the engine sound so smooth.but it has no power at all. it only just pulls away with your foot flat to the floor.

i've serviced it with all filters and oils
checked fuel pressure going into the regulator and its around 5 bar constant
i've checked all turbo hoses ( recently silicon ones )
checked all the connections
nanocom and test book show no faults at all.
i've replaced the cranksensor maf and map
I've re timed it 3 times just to check. crank and cam locked with pins.
all injectors are coded correctly and in the correct positions
injectors were adjusted wound down and backed off 1 turn

apart from the pressurising of the top hose it went like stink. i could light all wheels up from a stand still and now it hasn't got the power to even pull away. it also tops out at 55-60 when i used to do double this ( where legal :p )

i'm at a complete loss. my local dealer is also stumped and i cant find anyone else with this issue with a cause or solution .
