The problem is, that you must correct the hp to compare US dyno runs with german dyno runs.
1 bhp or 1 SAE-hp = 1,014 german DIN-hp
If you have 200 SAE-hp at the crank in US this are 203 DIN-hp in europe/germany
I see you have a 5VZ-FE at 4psi this are only 0,28bar the TRD compressor makes 0,4bar = 5,8 psi I think.
You get 197,8 whp = this must be corrected around 221hp at the engine this is corrected with *1,014 = 224 DIN-hp,
My N/A engine has 191,8 DIN-hp on the wheels and corrected 211 DIN-hp on the engine.
But you get 242.30 torque, this is corrected with *1,36 = 330Nm I get only 243Nm.
I think you have only less power on your turbo charged engine, but you have your highest power output at 5000rpm I get it at 6550rpm and a fuelcut at 7100rpm!!!
Your air/fuel ratio fall down after this point, do you use the 200ccm injectors?
Perhaps the 5VZ-FE has a very low fuel cut or your fuel system comes to the dead line.
Normaly the 200cm injectos are good enough up to 240hp at 3bar fuel pressure.
You should try to drive higher rpm, then you get better power output.
Thats why the 5VZ-FE is not a good choice here in germany, there we get problems with the top speed.
Can somebody confirm that the automatic 3VZ-FE have a lower fuel cut like the manual transmission?
