i know my t25's stock wastegate is set at 8psi, but for now i just want to go about 5-6. are there any weaker springs out there for this? and if so, how do i open the wastegate actuator?

 

You cant. Just run what you have or do something I don't suggest, Lengthen the arm.

Or find a t3 5.5psi wastegate.

 

not much of a choice but to run it as is, dicking around with it will cause problems down the road

 

Or you could always use the *Gasp...OH NO* carb-spring approach. I tried this out on mine for a little while and believe it or not, it worked ------ awesome. You take the twin carb spring setup that you would buy for a holley 4-barrel carb and attach it to the wastegate flapper. Then stretch the springs up to where the rear water coolant line is and attach it there. Gave me a steady 6 psi all day long with no issues. It's ghetto, but it works...and it creates a great conversation peice for the suckas that try and find the wastegate
