Boomer (Rich), Welcome to the forum;

Congrats on your dual purchases of your PT's. I'm not sure about the shimmy in both cars, as being so new it leaves things out like bent rims and out of balance tires. I can tell you that the delay in taking off from a start can be cured by a better intake with less restriction of air. Even modifying the OEM intake like a few have done on this board with a larger nozzle at the input side and doing away with the silencers would probably help...but I do know the hesitation went away with mine as soon as I changed intakes.
