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

check your coil, a friends mr2 3sgte wouldn't boost right when his coil was bad!!
