So, my automatic Nissan 350z 2003 has been giving me issues when drifting. It loses power slowly even when my foot is all the way down (does not redline when foot is down) and gains traction. Due to this, I resulted to make a by pass connection, which completely cuts off traction control (because when the TCS button is pressed, only 70% of TCS stops functioning). This by pass fully turns off TCS and VDC (also turns on brake warning light and abs warning). I researched that this connection was supposed to fully unrestrict the car when drifting, which was the case for my first lap. The car was performing better than ever and had so much power. After that, I let the car est and went for my second lap, but something was not right... The car felt sluggish and was just losing power, and since then, it just kept on feeling the same. Normal driving feels just alright, but only when drifting is where all the issues arise. Please, if you know anything about this that could help, let me know, I'd really appreciate it.
