i have a hx35 on right now and it works graet i also have a h1c and on the wastegate it say big head banks and it also says 43psi would my truck be better in the long run spoolup quicker or slower? egts? overall performance?

 

i currently get 35psi is that too much?

 

35 psi from an HX-35 is about max for efficiency.....Not too much.

You would be better with the big head due to the fact that you can adjust it to 35psi and slow down on the boost kreep. That would give you better bottom end and midrange on the torque rise.
