You mention a fan loom. Did you buy the loom kit from MSD/Autodynamix? I fit one on mine last month with an 82 degree stat and uprated switch. I cant believe how powerful the fans are now and how early they come on and after a drive the fans still run. It wasnt nothing like that before.
Ive just gone and bought another loom kit for my Escort RS turbo too.

Also you mention about the car pulling to the left. Did the tracking/alignment sort it out? Mine handles like crap at high speed. I should really get mine set up.
