Still got the turkey but that was to be expected. -____-
No it is not.
the forge is usually sold with either a green or yellow spring. almost everyone orders the stronger spring
to get rid of turkey all you need is the softer spring. most have the stronger spring installed as it would vent a bit, but not enough to cause the car to stall with the MAF in the stock location.
now that you have the maf relocated you can go ahead and install the softer spring without worrying.
here is what it will sound like with the softer spring installed:

As you can see there is no turkey whatsoever using the forge with the softer spring.
also the stock plastic hot pipe has a very small nipple which is easily crushed when tightened too hard for mounting the forge BOV.
I found that enlarging this nipple when i changed the hot pipe to metal instead of stock also increased valve performance.
Essentially people that are still dealing with turkey after relocating their MAF either have:
1. too long of a vac line to their bov causing reduced valve performance
2. too stiff of a spring in their valve ("non adjustable" valves like the forge will need the entire spring changed to be "adjusted")
3. they have a BOV with an adjustment screw and they have not set it to be "soft" enough
4. a combo of 2 and 3
5. too small of a nipple for the bov/bpv to function properly (or the nipple is crushed in a bit if using stock plastic pipes)
6. a crappy bov (though this is very doubtful as even my $35 ebay bov that I am currently running works awsome, you just need to set them up properly)
