Leaving the fans on won't make it hold the same temp from staging back to the pits...
either way as Lee stated sounds like the carb is still very fat,,and too gain .2 arlready on a fat tune,,means there probably another .2-.3 still there was you get it dialed in.. 8)
Congrats and good luck.. 8)
I never had any luck with my prosystems carb and their vacuum regulator set up. I ended up ditching it and putting my Magnafuel back on to make sure I didn't have an issue. Fuel pressure was all over the place. Now I am running an aeromotive return regulator on ethanol.
