Very disappointing low dyno numbers please help!!!!!!!

Jordo!

Those intakes probably introduce too much turbulence to the MAF sensors, causing misreads. Either toss them for stock + high flow filters or the stillen G3's and retune.

Also, keep in mind that even with SAE correction, if the ambient temps were radically different during each time you dynoed, that will throw things off quite a bit.

As to the octane issue -- run 95 RON and you will be fine.

I'm afraid I spent way to much and love these intakes way more to just throw them aside loool isn't there another way to perhaps fix this MAF sensors issue if there is one that is, without having to change my current intake setup?

As for fuel I'm afraid that 91 is the highest grade that we have here

Jordo!

It depends. If it's a constant misread then yes, with tuning. If it's a random intermittent misread then you'll have to experiment...

Does the location of the MAF sensors change from stock? That alone could be the cause, and if so, it should be a constant error that can be fixed with tuning.

Another possiblity is the filters -- if they use the HKS style "mushroom" foam filters, I'd swap them out for larger ones made of oiled cotton (e.g., K&N) or dry synthetic (e.g., AEM).

If the 91 is AKI (RON+MON/2) then you are fine. If it's 91 RON, that is basically 87 AKI (i.e., "regular" unleaded), which is too low an octane for the Z.
