The shop has to prove that your performance mod caused the damage. So at least you can get the computer tuned.
I know how to fix your tire squeeling...Stop racing next to Jethro because when i raced him my tires squeeled also and when i was alone they hooked up. Did he happen to get out of his truck before the race???.....if so maybe there is something fishy going on with Jethro that we need to investigate.
HEHE JK Jethro. Your a great guy and fun to race next to.
