Ok, the A/C is on the fritz, and they are telling me it is the PCM program not turning the fan on when the A/C kicks, and the A/C is reading over 400 something on the high side (I am not savvy in A/C techno-speak)

They don't want to run diag. on it because of the tune & supercharger stuff. How far can they go without hurting the tune? Can they diagnose without reflashing safely?

Over my head here, and the 95+ temps are cooking my head.


Thanks in advance guys,
