05 d4d loss of power

[Myluxy01]

Hey guys tried to get a tune and only making 65kw befor tune and then after the tune 85kw at the rear wheels. I have replaced injectors and suction control valves and replaced filters and cleaned fuel pick up and tank for any contamination. And the hilux still cant drive up it has barely any torque but when it hiys boost it runs okay but then drops off for a split second and then back on its a massive notice in power loss there but im stumped as to why the car only makes 65kw at the rear wheels standard then after the tune its about 85kw can any one shed some light on problems they have had or other things i should check and the tuners cant seem to find the problem by pugging it in everything looks normal

Not sure what the problem is maybe injectors them selves FYI mine is making 129 Kw at wheels with exhaust and steinbauer chip .Maybe timing is a tooth out on belt but I'm pretty sure they don't run at all if out.

Have you tried cleaning the MAF and MAP sensors? Dirty MAF sensor can make boost issues and loss of power.

Also the EGR clean may be something to look into.
