Your damper has probably an O-ring on it. Push the O-ring all the way towards the damper. Open the damper valve with a lever. Get on the e-bike. Get off the bike. Now, measure the distance between the O-ring and the damper. The correct sag value should be 25% of the total length of the exposed damper cylinder.
Rock Shox says you should first try with the pressure in psi equal to your body weight in pounds. 130 kg is 286 lb, so the initial pressure should be set to circa 290 psi. Only in case the O-ring slips a lot during your test, you should increase the pressure. I rode the Trance with an initial pressure 260 psi. As I weigh 230 lb, the initial pressure should be OK. However, Rock Shox might have forgotten about the suspended e-bike weight. Mine is 26 kg, and the suspended part might be 22 kg. 105 + 22 = 127 kg (280 lb). I used 290 psi and am good.
You are 130 + suspended part of the bike 22 kg = 152 kg. It is 335 lb so 335 psi. However, you absolutely should do the initial sag test first!
