safe mode! please help? Options

Ok, heres my delima. Ive had my 1995 celica gt with the 3sgte for about 6 months now. Ive had an on going issue with boost not going past 7-8 and it goes into safe mode. Heres what I did to try and correct these issues.

-front mount intercooler 26x5.5x2.5
-aluminum 2mm thick mandrel bent intercooler piping
-header wrap on intercooler piping anywhere it may get hot (photos in my profile)
-rerouted intercooler piping away from exhaust as much as possible.
-ngk spark plugs BKR7E (gapped at .032)
-installed tvsv led monitor green/red
-disconnected stock gt exhaust and running 2.25 (after engine is open)
-xs power 3" dump pipe

I dont understand what exactly (other than knock) will cause the 3sgte to go into low boost mode. When its 80* outside and Im at a light it will go into safe mode. Once Im on the road moving for a minute or two it comes back to normal. Is this normal? Does anyone know what symptoms will cause the 3s to go into low boost mode? I know when its cold it goes into low boost mode, if it gets to hot will it do the same? Thanks

you should also do the multimeter tests on your afm. there is a temp sensor inside of the afm... normally it will put the car into low boost mode when its 40deg or colder outside, but if the sensor was bad, it could start doing it in warmer weather conditions.
