Oil pressure more important than temperature?

Tractionless

Aren't AEM and Defi part of a system with a controller?

Not wanting that. Looking at Prosport JDM's now.

I'm not sure about AEM, but Defi has a few different lines. The ones I have are the Advance BF line and they do require a controller. It's nice though; the controller provides some nice features. Plus, it allows you to daisy-chain the actual gauges. So, in my case, I have the controller mounted under the dash, and I have all my probe lines running into the engine bay (this you obviously have to do even with gauges that don't use a controller). But with the Advance system, I have one 6 foot cord that goes from the controller to gauge A, then there is a six inch cord from gauge A to gauge B, and another 6 inch cord from gauge B to gauge C. They say you can daisychain 8 gauges on a line like this, and there are two lines available. It's like an extra $130, but well worth it in my opinion.

Having said that, I believe that the Defi Racer series does not use a controller, and they look similar to stock also (but not as much IMO).

I have the Defi Racer, no controller needed. Itll be a stupid amount of wires if you're running three Racer gauges tho.

That's why I happily paid a little more for the controller version. There's not a ton of space behind the dash.

Depends on what you mean by unstable. Your blood pressure fluctuates just like - maybe similar to lol - the oil pressure. 5 PSI sounds like a normal fluctuation.

Oil pressure will fluctuate some. There is a lot going on inside a engine. If you are seeing something like 5lbs. Then I would start looking.

Yeah, sounds like you should pull the gallery gaskets and toss a new oil pump in there while you're at it
