Planning on changing my injectors today for 650 cc on 04 sti, would it be ok to drive for a couple of weeks till i get it mapped.

Thanks Rob.

 

IMO it won't drive as well as normal. Best to drive it off boost wherever possible. You should leave it as long as you can before changing them!

 

As above,i only went from 380's to 440's two days before mapping,drove ok,idle was a bit lumpy,but never came on boost once.But do you want to be running it like this for two weeks? It would be over feueling,which could cause problems.
