Yeah, but when you are turbo and maxing the turbo to the engines potential. You will get much more power running a more advanced ignition and proper AFR than to just lean it out. If everything really is in order, and the tuner didn't do it then there is another issue. But, my finger points at the tuner because he built the car as well as tuned it.

I do not think it's the turbo though, if it runs out of air at the top end, and the injectors are still injecting at the same constant then it would be rich since not as much air is getting to the engine.

And how would you just disable VVT-i like that? Just unplug the solenoid? ehhhhh? I don't think thats the proper way.
