adjust it...

or are you adjusting it and nothing is changing..

do you have supporting mods to be raising boost?

Have you checked for boost leaks? How are your spark plugs? Is it sputtering? Did you hook the boost controller up correctly?

no its called the shit turbo xs controllers they spike like a mother fucker and also they really get funky since the pressure change in the air...

ive been adjusting it for hours...got the basic upgrades but wonderin if not having a downpipe is affecting it much...im about to change my spark plugs to see if thatll make a diff...at the same time look for any leaks but thats a pain in the ass haha

Looking for leaks does not work. You have to use and air compressor. To pressurize the system. DO NOT use over 30 psi. Look on supraforums for exactly how to do it. I've done the "looking" method and still found 3 leaks after I pressurized the system.
