Just to verify, the set up for this car is:
3" Bosch MAF
BBT K300 Turbo
Bosch 550cc Injectors
FMIC and 2.5" Boost Pipes
Badger5 Supersize TIP (the silly big one)
Had a GFB DV+ Re-circ, recently swapped to Stock to see if it makes a difference - it does not.
Running V-Power Fuel
Fresh Oil (Quantum 5w40 Fully Synthetic)
Fresh Plugs (NGK Platinum - PFR6Q)
Standard FPR, but has uprated fuel pump.
SAI Delete
N249 Delete
A bit of background
The mapper who was working on the car said that boost was all over the place when he was attempting to use the N75.
We have since found that the N75 was tubed into the Intake Manifold (Post Throttle Body) and instead we've re-routed it to Pre-Throttle body, running directly off one of the boost pipes.
He said fuelling was A-OK and that it wasn't a problem.
It's really weird, it looks like the car can acheive the power I wanted, but it isn't able to sustain it, or see an increase up to 6.5k rpm.
When doing 3rd/4th gear pulls - the car maintains boost all the way up to 7k RPM. Going by the boost gauge in the car, it'll run at 1.3/1.4 bar and gradually slope off to 1.1 bar by around 7k rpm.
N75 will not work properly if routed post-throttle, anyway if tuner cannot reach some good result then he should tell you thats the hardware problem here and hes not able to continue. but he wont, instead of it he disable PID regulation and made some shit.

TEMIN - The minimum amount of time the injector will remain open during a cycle in millaseconds.
do not touch all of these
read wiki, most of answers there
go back to basics. start from scratch and do emissions
flat fkkvs, tvub, krkte, kvb for basis fueling
mlhfm and kfkhfm from ecu originally maf comes from,
now log mixture, boost, timing, knock etc and tune until you get all the things done
raise ldrxn and kfldhbn a bit and so on
this works until 1.2 bar boost and 180% load. next thing is iop/irl rescaling, lots info here
there is no rocket science its covered 1000 times.. pid maybe gives you some headache on a hybrid but thats all see here
