1. Avoid low and high boost. There is no benefit, don't want boost, remove right foot from loud pedal.
2. For the boost levels you have mentioned, I doubt there would be any gains by swapping the waste gate actuator.
3. What turbo will determine the best spring, so post that up please.

14.5 (1bar) spring

yeah i had a forge acutator with the 1bar spring on my vf37 running 24psi, worked great until the motor decided enough was enough

same here a forge actuator with I think either a 1 bar or 1.2bar spring and running 26 psi on a VF37
comes on hard and keep going till the end

also get and a 3 port boost solenoid like a grimspeed

What kind of power you making with 26psi? Graph?

Putting an eboost street in it?

this was mine running 24psi with a vf37

jdm 207 didn't like it though resulting in the piston skirt letting go & throwing a rod through the block, damm hypercrap pistons

I personally wouldn't recommend anymore than 22psi with a vf37 on stock jdm 207 bottom end, this is about what burke & russ are running with reliable results
