ok so ive done some work to the bus (a.k.a wrx) but even before it had spike also, the work i did to the wrx tho is :
-td05
-STi t.m.
-450cc injectors
-3"ss turbo back
-fuel pump
-pod filter

now im getting my tune done soon (like wen i get my licence bak) nd im wondering if the tune will fix xum of my spike, if not is there a way to reduce it a bit, i kno if i put an electronic boost control it would but dont no if that will stuff with my tune,

punctuation and spelling will go a long way to helping you fix the problem.

boost spike is normal from factory, exacerbated by 3" exhaust. Proper ECUTek dyno tune with manual or electronic boost controller (I'm running a manual and it works great) will fix it no probs

450cc injectors? Do you mean 440cc yellow tops?

from what i'm lead to believe, if you've got a mechanical boost controller - they generally spike in colder weather - which we are definately being exposed to at current.

remove the manual boost controller, add a propper ecu or at very least a unichip piggyback ecu, no more boost spike

hes got the unichip to go in when it gets tuned
