thirteendog i would do the cooler and pump before anything else. im right across town form you and the cooler made a world of difference in the iats and s/c shutdown. in conjunction with the supercooler i added the cm30 pump separated the coolant from the i/c and added a 180 tstat . on my dyno tuning session tony will do the -10* fan mod.
after the cooling mods you can rest easy as no more s/c shutdown. then the cai pulleys and then tuning
