A spacer or plenum mod will easily do 20HP when FI. At least to me that's a good bang for the buck.
Test pipes Ditto.
A good catback exhaust system Ditto.
A good FI system will always have these elemental boltons.
The others can be debatable. Cams obviously perform when FI, but the installation isn't so simple like the above mentioned.

IN ANY CASE the plenum spacer and testpipes are the best cheapest mods you can do

Not really. For 6 grand, you could get an APS single with APS exhaust. If you do install, you can easily be at 400 whp for a total of 6K bucks.
What other supporting boltons are you referring to?

APS single bolted on with APS exhaust will get you near 400 whp. Nothing else is needed, not even test pipes
The one I installed had nothing but a UR crank pulley and the APS exhaust. The guy had under 6 grand into the setup and pulled 406 whp

40HP would be a mod very well spent.
406 HP - stock @ ~240 HP = ~166 HP gained by the turbo.
Tubo = ($6000 / 166 HP) = $36.14/pony
FI Bolts = ($350 / 40 HP) = $8.75/pony
By any measure the FI bolts are a super deal!
Even if it is chalked up as ricer math at 1/2 the gains, its still a tremendous value.
And is safe to say (even under a worst case scenario) test pipes and a plenum mod can easily gain over 20 HP on a FI system.

you dont have to do that tony to show you have a good product.. I am Fi and i have not seen an increase of more than 10whp with the spacer after many runs, but still its an excellent mod with great price, no need to resort to ricer math

one thing you are forgetting is that on a single turbo, you cannot use test pipes. Also, I have an aftermarket plenum, have seen spacers on FI, and would be surprised to see someone pull more than 10-15 hp out of one. That is the beauty of FI though, you just gained 150-200 hp, so who really cares about the extra 10 hp. The N/A guys will drool over a 10-15 hp component.
That said, with a tune, test pipes could alone add 40 hp to a TT setup

I don't know what happened in your situation but I know I've seen multiple independant pre/post polts of plenums and spacers showing no less than 17HP when FI. Three of them were insatalled while on the dyno and with nothing else changed.
The typical range is 18-24 HP.
They won't be easy to find, but they are posted here on MY350Z.

There are three members I recall that posted their FI spacer gains.
All of these were results measured without taking the car off the dyno.
ZBOY made ~17.5HP on a HKS SC @7 PSI
350ZNV made ~19.5HP on a JWT TT @7 PSI
RandysG made ~21HP on a Vortec SC @8 PSI
PM them for verification.
If their independant results are valid and typical (not rice) that puts the average plenum mod gains at just over 19HP.
If test pipes yeild 40HP when FI then the value is even better. (Lets not include the cost of a tune because most FI systems should be tuned anyways.)
With 59 HP gained for $350 on a FI system, there is no better value than this.
