90 GST won't build boost past 10 psi

[Dave4g63]

today i installed an Ebay mbc a boost gauge and i also cleaned out the inter cooler.after i got everything back together took the car for a spin but it won't build past 10 psi im not 100% sure i installed the mbc right ,no instructions.. i have got pictures of how i installed it that i will include in this post. current mod list is down pipe, straight pipe . k&n filter with removed can and the mbc. so don't look at my profile for mods thats my 2g's list i plan on a blt but i want to make sure i have this thing hooked up right, its a bit different than the ebc on my 2g. thanks

Why did you have to get a crazy ebay MBC? They don't hook up like the normal ones. I remember seeing a thread in the past month or 2 that had a picture/diagram of the proper way to install that thing. I'll see if I can find it.

Edit: Found it!

The whole thread can be found here: Installing Ebay MBC

Hope this helps!

I've never seen one like that either. I mean I'm sure it'll work fine once you have have it hooked it correctly. I diy'ed mine from home depot and boosting 17psi. Also check the couplers holding the piping to the intercooler and make sure they're tight
