How much boost should I get with LMS 3bar tune?

A couple weeks ago I installed the LMS 160* t-shirt and 3 bar along with their tune. Right now idle Temps are 178 to 185 and boost is max 14.7 psi but usually high 13s just like it did with a 2 bar. I thought with the 3 bar I was supposed to get something like 16 psi. Is everyone getting the same boost as a 2 bar?

With the 3bar Livernois introduces boost earlier and more evenly throughout to get more power. Less boost spikes for better efficiency and wear and tear.

The 3 bar is being used to more accurately meter the air, as it is supposed to have more precision in addition to range over the 2 bar MAP.  You could have them turn up the boost, but the stock turbos start losing efficiency after 18 16 psi or so, I believe.  Have to look at the specs again.
 
From our former SHO owner Dave and his dyno time I'm pretty sure he was at mid 13's for boost. I could be off on that. With torque I've seen spikes up to 16.4, but that's torque which is a bit off in this area.

Wass, what are your cmc and iat 2 temps at?

How hot do your cats get?
If my ambient temp is around 80 my intake temps are usually 5-10° hotter. Then after the intercooler before the meth nozzle it's around 130° then after meth the sensor on top of the manifold reads around 40° in just seconds after spraying. No idea on the cat temps. I'll have to see if there is an exhaust temp pid.

Before meth it's just normal temps. after 7 psi meth sprays and it says under 50° from 0-140.

It wasn't bad installing the boost gauge. It made it easy to install the meth boost control since I ran a vac/boost hose into the cab. Very little wiring,  just pos, neg, and headlight dim trigger. It has a boost sensor that you mount below the dash so you don't need to run a hose to the gauge itself. I love it.
 
What kind of a tuner are you running to read that many pids? i hope my X4 can do that!

Sorry for the bombardment of questions lol
 
With your x4 used as a bridge with a powerful laptop, you should be able to log quite a few. I have a new rig so I plan to find out while I'm off next week.
 
I have a lap top with live link that i used for data logging. It had a ton of pids but i only used the ones torrie wanted. Plus lot of them are kinda gibberish to me. (rookie)

No problem with the questions. I use the x4 to datalog for Torrie. When I'm just driving around I use my phone and a Bluetooth adapter for the torque app.
