Eagle Talon and Mitsubishi Eclipse turbo models run 7lbs of boost as a factory setting.
you might be running too much boost off of your turbo especially if youre running a stock turbo
Get a manual boost controller ...
Dead cell in the battery or corroded or loose battery cables.
1994 Mitsubishi Eclipse. I disagree, I think Boost is an R34 Nissan Skyline.

The website does not exist now, but Boost was, indeed, a 1994 Mitsubishi Eclipse.
yes all you need is a boost controller
If it hasn't got a turbo there's no place for it to get boost from.
the normal boost is 5-12 psi. the normal vac is about 18-20 psi
In most cases you use some type of manual boost controller between the waste-gate and a good boost source. Or you can use some type of electronic boost controller but this can be expensive.
Make sure the boost air isn't escaping from anywhere; for example the piping which runs from the turbo, to the intercooler, then to the engine. If any of this is split or frayed then your engine will be getting a lot less boost than it is supposed to. As well as this it could indicate a faulty turbo. Or a faulty wastegate, in which case you will need to replace the turbo unless you have an external wastegate, in which case just replace wategate
most engines without any mods will hold up to 5 lbs of boost...anymore and you need to adjust the fuel
