Anyone have a hahn wastegate that actually spikes and maintains the same psi till redline?
i had the same problem with the heavy "and overpriced " wast gate and tru boost untill i found my boost leaks when i went to do a tune run i had all slack taken out of wga arm "and the canector on the end" tru boost set on 30% with spring of 26 psi ,the first run mashed gas and i herd loud machine gun sound so i tried it again 34psi!!!!!!! pulled like hell i was pushing like 22 at 3500 rpm loud machine gun noise again , last run turned off tru boost mashed gas 36 psi "thats what the gauge said but its not suposed to go that high" loud brrraaappp then pop ic blew a weld about 8" down the side of end tank, well the point of this is the turbo system is sound wga is good like me you probly have boost leaks that dont show up untill around 20+ psi "i drove around for 6 months with bost leaks cursing hahn" check all ic/boost hoses clean them out and use a small amount of hair spray on the hoses to reconect this will lock them in place,
these symptoms are almost identical to mine
oh if any one else has had that loud machine gun braaappp sound please let me know what that is
ARe u nutz??? oh yes u are. lol why r u boosting/spiking 36 34psi that is wrong mang.... wut r ur mods?
it was a mistake thought the gauge was malfunctioning till ic blew up
