New Product--Tester

you should send it in and get a rebuild on that pump. where you using water or alky? either way sounds low and you should send it in.
 
We have an older (2005-ish) pump that with the tester, struggles to get 155.
This was with a battery charged up fully, the gain knob at 8, and the initial at about the 1-2 o'clock.

Is this "normal"? I also notice a lot of oscillation on the needle at full pressure, it swings from around 130 to 155 rapidly.

Car seems to perform ok, no knock or any apparent failures in the system, but I'd like to be proactive on the pump rather than reactive if this sounds like the pump is falling down...

155 is not that aweful, but it is down on pressure. Hard to tell on pumps Pre-Dec 2005 era as internals changed on what I supplied. Your more than welcome to send it in for inspection.. take it from there.
 
Call and order or I can send you a request through paypal. PM me your info if you want to go that route,

Julio
