Same here I run a RMV speed 2.5 clutch setup..1.1 springs and either 3 alloy or 2 alloy and 1 carbon on looser tracks..I agree with grizz1 it bogs just a fraction out of the corners using 1.0 springs..spent a futile afternoon 2 years ago when I first started with the GO 7 port trying to adjust the tune to lose the bogging..Then just as the day was ending I thought "hmmmm CLUTCH" swopped the springs and promptly lapped everyone who'd been catching me out of the corners all day...Muahahhahah!
