Hi guys New on the forum Need hep with TiBurons

hey , new on this forum . I picked up 04GT 6speed over the summer for DD because my vr4 was no Good DD and was burning gas like V12 . I replaced Brakes and calipers , Rear big sway bar , sway bar links all around and made intake from intercooler piping left over from 3000GT vr4 . Still having few issues and need help from you guys

1)Traction! spins like no tomorrow ( 225/40/17 drag radials)
2) driver door lock gets hard to open and close(feels like electric lock motor is constantly ON)
3)Motor mounts. about to install 2nd set
4) after Reving , Rpms drop very slow and makes car hard to shift (has New IAC)
