Should i get new spark plugs?

[Boostedtsi0521]

So i just got a b16g installed with an evo 8 fmic and i have a 3 inch turbo back exhaust, thats it everything else stock. My question is when i i get on the throttle it starts to sputter at high boost like 18lbs. Is this spark plug related? Or just not enough gas? And how can i resolve this so i wont blow her up!

Do you have a wideband? If the plugs are good, try gapping them to .28.

You should lower your boost to 12psi & get something to tune with, best option is ECMLink. Bigger injectors once you have a way tune them.

You other post sort of alluded to this. you are pushing way too hard with no tuning and no supporting mods. This is a definite path to broken parts.

These guys are absolutely right.

Yes they are. Thanks alot but i left out another piece of info that i just remembered.
3k rpm and lower its its boggy and throttle response is laggy. As soon as boost kicks in its perfect. Wouldnt that indicate spark plugs?

Boggie, laggy sound more like a boost leaks to me. If you haven't done a BLT you should do one first & fix any leaks.

@Boostedtsi0521 So did you already check and fix all boost/exhaust leaks, all mechanical issues and the wastegate hosing as we discussed in your other post? If those are already fixed, then get all necessary supporting parts/mods, install them properly and then get it tuned. If you didn't do that yet, then as I already said, first things first before doing guess works. Fix everything and then go to the next step.
