Wow, that power band looks flat and real Laggy. Is that why you have cut half the graph off so you can't see it?.
It's an entirely new, never been done before turbo setup and it's on its 4th revision for boost tuning. It's had nothing to address spool up, or mid-range
Power. It's been all about finding the boost setting it likes without crossing the line with fuel. Besides removing timing to below stg3 OTS levels, then adding it back in, it's had nothing but boost tuning. I will get there.
But he is the cool part... I have two other turbine shafts I can use to reduce lag, and an entirely different smaller turbine housing. And if that doesn't work.... I have another compressor housing I can machine to a 20T ( 360whp compressor vs 400whp compressor that's in it ).
The compressor wheel on this turbo is bigger than a GT2860. And it doesn't have ball bearings.
The TD04 turbo is almost infinitely adjustable for incredibly cheap...
I'll post up some datazaps soon. But just like the 18 months or so it took me to tune my first cyborg, ya gotta realize, I'm not a pro-tuner. I'm just a guy with a relative understanding of turbocharged engines and some experience with access tuner.
TuningbyOZ will kick in at some point and help me with tuning the Vtak, VE tables and prob fixing a lot of mistakes.
