Default Alignment setup questions

Last year I installed new Michelin ZP tires and had a 4 wheel alignment done. Ever since then the handling seems to be different. The car doesn't track straight as easily as it should. It does not wander on its own but the steering is really sensitive and twitchy almost like an old car with worn out front end parts. I have the spec's on how it was set up. maybe someone could give me some insight on this.
Thanks in advance!

Don't suppose you have the readings before the alignment to coompare? My alignment man gives the before and after. Caster is a major factor in the car wanting to go straight ahead. Your caster may be a bit low. 6.9 on the left wheel and and 7.4 on the right wheel might be good caster numbers but it would be great to know what you now have. . Good luck!

+0.14 total toe in front may be a bit high, even if it's in specs.check your outer edges for feathering. Honestly, the feeling you get may be coming from the Michelins, they should feel a lot different than the other tires you had on before. A degree higher on both side caster may help also. In my experience when test driving cars after I align them is that it takes at least ) 0.8-1.0 degrees to see and feel a difference. good luck
