Update
Pidge, my dad and I were on the car the whole of last night, till 3!
Removed the powerboost valve, fitted a 3bar fpr that pidge has kindly given me a lend of N249 and N112 bypass done thanks to pidge's soldering skills. SAI removed and forge blanking plate fitted, and n75 changed as I still had the c version on the car so the updated F went on. All the vac lines replaced and tidyed up and hidden away.
Pidge noticed that my dumpvalve wasn't working, after some investigation the pipe work was on the wrong way on the actuator ports, It still wasn't right so dumpvalve off and taken apart cleaned up all the old grease and refitted and tested for vacuum all was fine. Disconnected the battery for 5mins to reset itself.
Took the car for a run and there was hesitation when the car as under load between 4000rpm and 5000rpm, after a quick search on here it looked like it may be spark plugs and coils,
Coils and sparkplugs taken out to find the spark plugs really sooty cleaned them up and back in they went. 2nd run of the car and the car was backfiring repeatedly at 4000rpm. I know that the car is due a service so oil and sparkplugs will be getting changed soon, and will check to see if any of the coils are weak or just knackered.
I haven’t had the chance to get the car up onto the ramp to have a look at the lambda connection but should be within the next couple of weeks.
Also my secondary water pump is running excessively long after the car has been switched off and need to pull out the 30 amp fuse nearest the wing on top of the battery to switch it off, could this be why that fuse melted before? New secondary water pump needed?
I’m sure pidge will correct me on anything I’m wrong In saying
