s13 turbo jumping

[ODB]

when i get in the car and start it, i let it sit a couple minutes to warm up, and when i start to drive and get into it, it jumps back and forth like the boost isn't being delivered properly, i have a boost controller and it turned down on low and high boost, and the gain is on low too, just wondering if anyone knows what it is, or if its my driving or something with the engine or exhaust, thanks,

bad bov or wastegate?

remove the boost controller, test.
if its still fucked, then at least you've eliminated one possibility.
have you inspected the turbo?

Also it could be a boost leak somewhere, check your intercooler pipes/couplings for leaks. Make sure you plumbed the vacuum source correctly for the boost controller. Like brndck said, unhook the boost controller, see if it still does it, if it doesn't, then there is something wrong with the installation of the boost controller or you're trying to run too much boost which is maxing out your injectors.
