A mbc can't "be set to", if you have consistent temps, then i could see this. When i ran mbc i would see 14 @ 85°, and 5 hours later @ 55° coos see as much as 16-17 psi. Bottom line watch/datalog your boost.

Aem gauges i believe can't read below 10:1.

Also didn't see a mls hg? Is be worried of blowing the head gasket around that boost.

Still running the stock hg, that's why I'm not going above 16 psi. I watch my boost like a hawk and it never changes, I did some research and found a high quality mbc that does not very.

Ya my gauge reads from 10-1 to 20-1

i would get an aem "true boost" it can shut down the boost kind of like the stock pcm if it sees over boost, and log your boost, and be used with the plug and play. i have one on my red car, and if i raced or wanted to trick out my black car she would have one already. it really saved my ass one night.

i also would not mess with the maf. find another way to tune it, like an adjustable fuel pressure regulator.

agreed, those are what i use in my black one. they are fine, but ive seen them tend to get off over time(boost gauges) my brother in law was messing around in his evo, never realized where the gaugue sat when off, it read "25psi"......the computer saw close to 35 when cyl #3 desided to take a detour out the side of the block.........then 20 mins later i met my wife for the first time :twisted:

AEM has a new boost controller and wideband all in one called the fail-safe. It it goes to lean it will cut the boost and possibly safe the motor...... look into that it's pretty awesome.

AEM = Another Electrical Mistake

You may be crazy, I have used AEM, haltech, linkG4, Apexi PowerFC, Bigstuff, and OEM GM with HP tuners.... my AEM EMS series 2 is packed with so many options without the need to go buy other items. Boost control, anti-lag, two step, multiple ignition patterns, yada yada yada. Other than some motech controls I am very pleased with it. All for 1500 a few sensors and I'm very pleased.

Would it be a bad thing to use an apexi safc? Would this help with my maf possibly being faulty?

:) it depends on how you use it...
I drive my car since more than 3yrs with safc. I set it self and install it self. No problems :) but it can be horrible if you don't know how... You can damage the engine.

I am not a fan of SAFC, but they can get the job done on a budget. I prefer other solutions such as a standalone which you can do for about 800+ depending on your level of comfortability.
