enough said, pony up the extra 40 dollars for the real tial 38mm or youll be spending the wg money twice like i did and a hell of alot more to rebuild your blown motor when the wastegate fails.....

but, if u wanna learn the hard way be my guest.

 

I have one and it has the 5 pound spring in it and it pushes around 8 psi or so! Not sure whats up with that! But other then that it seems to work fine!

 

mine took a crap after 3 weeks at 9psi on my turbo focus.

the diaphram just blew apart.

also they said they gave me a 8psi spring, but when i ran it. it was like 12

 

$40 extra? ---- more like double
you idiots need to run some sort of boost cut; uber does it; crome does it; dunno if hondata does it; all the major ems's do it.... I'll be running it
