Slip adjustment on a Stage 3 2015 RXT 260

The slip setting shown is for a high performance Seadoo using aftermarket supercharger parts. The principal of adjusting slip is the same for stock models, but target slip would be much lower.
The 2015 RXTX was heavily modified by a friend of mine, including addition of a new supercharger wheel with 16psi boost target. After less than 10 hours, boost pressure decreased along with RPM. Peak speed of 83MPH lowered to 74 MPH.
The supercharger clutch was readjusted for slip, apparently the rule of thumb is 1 ft/lb slip for every 1 psi of boost/discharge pressure. Test run is next week after weather clears.
Tested a digital torque wrench vs dial indicating with memory needle. Really like the memory needle better, gives a better visual on slip. But either will work.
(Man this ski is so nice!)

Hi What should be the slip on the supercharger with an all stock seadoo RXP260RS 2013 model ? Mine has been rebuild, but the SC is out the ski now since been doing the Carbon seal. Just want to check the slip before I put it all back together Thankyou !
