so i went to 2 diffrent import store and got 2 totally different answer. i have a 38 tial wastegate and i needed to buy a 10 psi spring. so one shop tells me its the same spring for both 38 and 44 and he gave me a big yellow spring. when i got home to change it, my wastegate had the small red spring in it. the big one fits perfectly but i wanted to ask you guys before i put everythyihng back together.

 

did you look on tial's web site??? they have all there own products on there and the size and pressures of each spring in each gate.

 

He gave you the correct one, big yellow is 10 psi, the small red you had in there was 5.8 psi.

 

10.153 psi is the large yellow for a 38mm wg
