i agree with izso. try check spark plug first, then start from there. if the jerking hard+sharp, normally its ignition issue. try check also worn out or loose socket. mitsu have alot of reput socket.
Can but electronic better, more convenient and precise for tuning. For manual maybe try Turbosmart.hi guys manual boost controller can use? which brand is good?
actually this car installed with blitz sequential SBC boost controller, but the previous owner say the face unit stolen during a window break
i found the Blitz sequential cpu? box and the SBC unit in engine bay. need to dismantle it and change to manual boost controller (no budget for this)

Cheap ones mostly fakes. Buy from trusted sellers like N1, Everco, etc2. Not sure about Arospeed. My Evo now uses Arospeed FPR from previous owner and seems ok but for important stuff like boost controller I would probably prefer well proven top brands like Turbosmart.turbosmart some place selling very cheap some place expensive donno which is original?how about arospeed taiwan reliable?
