Prop Slip ??
 

Have done my prop slip and by using a 32 box stock 4 blade bravo and entering 31 for it i have 14% slip.Will a 34 labbed give me or get me more slip.I wasn't able to get on plane with a set of 34 box stock but used a set of some kind of labbed 34's and got 5700 rpms and ran 97 mph but not sure what was done with the labbed 34s.
