During my testing, my TAS was reading 10 MPH high at top cruise speed. I did some research here and tried taping some o-ring material behind the static ports. It worked perfectly and my TAS now matches my averaged GPS speed. Fortunately I am getting Van's numbers at cruise
My problem is that it seemed to drop my low speed numbers as well. I was getting a Vs stall at 55 MPH and today I tested again and am getting 48 MPH, which is 7 MPH below Van's reference numbers. Is this typical when tweaking the static port? Does this point to a different problem, such as a leak? I tested for a leak in two ways and both passed (test via instruments at transponder check, as well as holding suction on static port with a very stable reading)
