reputation. I believe Ztuner has a bit more experience with the dw injectors then others and my stock turbo z runs fine with his 740cc dw chip. Make sure the chip is installed in the correct position. Make sure fuel rail is able to maintain fuel pressure...no pinched o-rings. Also, check safc settings.
