oem wga or fp hp wga
 

I have both, but I'm not sure what to use...

I currently have the oem wga actually on, but I also have the fp wga..

I don't know what the benefits for me since I don't plan on running more than pump gas boost levels currently, but possibly use meth in the future.

what are the differences between the two? I know the fp hp is rated at 18psi minimum....

My question I guess is does it hold boost better? I use a EBC so I am sure eventually I could max out the oem one....

if you have a ebc or control boost via oem ecu w/gm 3 port solenoid, fp 18 psi actuator all the way.

i have the 18 psi unit on my grn & love it. it should be fine on a oem e9 turbo
