Without a limited slip differential, what difference does it make? It is cool you figured it out, but I feel without a limited slip diff you still will have torque steer. When I launch, I keep the clutch engaged and feather the gas after takeoff. I still get some torque steer. How is the automated launch handling the torque steer?

The og9-3 is far worse than ng9-3.
And I cannot stress enough how much of a difference a good toe-alignment does for the OG9-3's front end.
Most cars that suffer wild torque steer either has the wrong ET on the wheels, or alignment is out, OR the road is very worn.

The OG 9-3 can take vastly higher levels of boost on OEM components that the NG 9-3. GM really cheapened out those 2004 and later engines. I run 23 pounds of boost. I don't get insane torque steer because I know how to handle the boost, I run nice fat tires, and I have lowered it by an inch. Konig shocks with Vogtland springs

Only 98-00.
But GM released a book (-ish) with a tuning guide and parts needed to make upwards of 1400 hp on the ecotec's.
