How do you replace the spring with the Hard Spring?

It came with the instructions but it doesn't have the spring installation or removal

Oh, how high can you boost with a HKS Dowpipe, HKS Hi Power Cat Back and an AEM Intake? via 91 pump gas?

Can it handle 22psi of Boost?

Any info is greatly appreciated.

Thanks...

unscrew the boost cap all the way out,and put the hard spring in.i would set it for 20-21.

 

Thanks...

 

The caps doesn't come off. The bottom does. You unscrew the cap to the end then unscrew the bottom of the MBC and the spring and ball will come out. Replace the spring the same way it came out and HAND tighten the thing back together.

 

EVOTEXAS,

How high did you set your boost with your current mods, using 91 pump gas?

 

I have the Hallman Evolution Pro RX and have the light spring installed. I am holding boost steady at 21psi...no problem

 

So do you think without the Fuel Pump and Dynoflash I can run 21psi too?

Here are my current mods

HKS Dowpipe, HKS Hi Power Cat Back and an AEM Intake gonna be using 91 Pump gas.

Is 21psi too high for that kind of mods without the Dynoflash and Walboro 255 pump?

I'm already using the soft spring that came pre installed, and its already turned all the way clockwise, Im getting steady boost of 20psi to redline, sometimes tapering down to 19.5psi

Oh anybody noticed the fast spool up? It seems to spool up faster now.

 

I hit 21.5 psi pretty much immediatley and by 7500 it has tapered to about 20.25 or so. I turned it up from about 20 psi after I got the pump and flash.
