gents, need help on Tial 44mm with 1 bar spring. i'm using tulang ikan, cheapo solution for boost control hehe. but the problem is the WG seems like struggling to hold boost really well even at 1.5 bar. it slowly increases. some says WG not big enuf, not enuf flow diverted. when I measure the WG, its ID is 44mm at the waste pipe but around 40mm at the valve inlet. so is it too small for 1.5 bar of boost? hate to spend too much on wastegate. pls advice.
