I just put a new motor in an spg and it is boosting way too much. The fuel pump cut out never seems to kick in - any way to test this? I was also wondering if anyone has a good way to identify whether or not an upgraded apc box has been installed and whether or not this upgrade disables the fuel pump cut out. I was getting boost readings of like 15pounds when I think its supposed to be 6 on an 88 spg. the motor I installed was out of a 91 turbo (red block). I utilized all of the original fuel injection except the injectors themselves which came with tehnew motor. The block I removed was grey I wonder if they are different or require a different boost setting
thanks!
