Needs an ARB.
I know what they are and what they do, but don't have any knowledge about the overall pros/cons on a street car.
You just cant take a corner at high speed. Everyday driving is fine. If you get overly concerned just disconnect one end link when not at the track and it is like it isn't there.
Getting close- Car was 1 mph faster in the 1/8th this last run but almost 3/4 mph slower in the 1/4 . was there a slight head wind? You said the da was better this last run surprised you didn't break 137mph.
What are your shift points set at?
The 1-2 seems very low to me. You want the car to stay in its powerband and its losing momentum shifting so early.
I agree it's definitely not optimal however it's not as bad as it would be on a N/A car.
Just fixing the shift points under the same conditions should net a 9.
Mine is stock, it came with the car......
