3 bar = 43.5psi
4 bar = 58psi

The fuel pressure gauge fluctuates so damn fast that its hard to read it, but its right around there. With my latency at 1.25 thats when my car really came alive, I hit 100 mph pretty damn quick, and its only boosting 5 lbs! Bad wastegate? Maybe. And yes I do have a Nismo AFPR.

It's actually the other way around. Running lean you will have higher NOx, Cat-converters break down NOx, but you need to be running rich for it to work right.

Maybe but don't have a leak tester to check, I will definitaly get to that though before I send off the piping to get painted. Although with the other engine it boosted the same exact thing and those pipes where really well made. I think the gauge just sucks really bad.Or maybe i just have a boost leak.

He came over today and we took care of some boost leaks, but what is really weird his fuel pressure was off a bit, so I turned it down and had it at a solid 58 psi but it like spikes every now and again and is not very stable. Anyone know what could possibly could cause this? Thought maybe just vibrations, but he has stock mounts.

is his fuel pressure stable at acc on engine off?

Yes The Needle Does Not Move. As Soon As The Fuel System Gets Pressurized It Stays There. Only When Engine Is Runing Is That It Goes All Over The Place, It Hovers Actually Around Whatever Pressure That Is Set At.
