I was woundering if there is away to lower the stock boost setting on a 14b below stock, could i use a different actuator if so what one or is there an addjustable actuator i could on the 14b.is there away to change out the sprinf for a lower setting one
thanks

 

I'm kinda curious as to why you'd want to do this?

 

i'd like to lower the boost on my internally wastegated td05h-18g. the actuator arm is long as possible already. i need a weaker spring i believe. or an actuator assembly with a weaker spring. they dont look like you can take em apart and swap the spring like a Tial.

tzsir, that way i could use the boost control solenoid. i'd like to roll off boost near redline for testing/ safety reasons.

 

Oh thanks, I never thought about it that way. I can see that as being a good idea.

 

You could try using a secondary adjustable spring which fights the stock unit's spring.

 

I lengthened the actuator on my t25 and it opened at about 5 or 6psi, only problem is it creates lag since the wastegate is always open.
