Injector swap of the same size, Retune required?
Hi all,
I have been donated some Bosch 550cc injectors by a mate. They are currently of getting cleaned etc etc.
I am currently running KSM 550cc's,
Once I have changed the dead times and voltage correction. Would I need to retune my VE table?
Cheers,

Take my opinion with a grain of salt because I have no actual experience with doing this, but I would wager a bet that you will need to do some slight re-tuning. I wouldn't expect for anything to be wildly different but chances are the fuel delivery characteristics between the two sets would be enough to need some changes in the tune. Even things like spray pattern differences could cause changes in your tune.
