would cause it to overfuel? without being remapped? basically want to fit everything but then have to drive to get it mapped...whats the downsides? lots of wasted fuel? any damage to engine?

It will over fuel as the duty cycle on your ECU will remain the same, so if you've got 50% larger injectors, without adjusting the map you'll be overfuelling by that ammount.

Basically yes, will bog down due to the extra fuel but won't be dangerous for driving sensibly for a 100 miles or so.

How far are u going? If u dive about for ages like that ul end up with bore wash(lack of oil because the petol has washed it all away) and u might damage the cat if u you have one

off or on boost, you'll still be using the percentage of injector size increase more in fuel, but will be fine

if its 1 or 2 mile yes - IF YOU CAN GET IT TO RUN.

190 miles - NO.

look up 'bore wash' on google.

You dont say what the old and new injectors are? They could have completly different charcteristics (delay/lag etc) as well as their obvious capacity

got an adjustable fuel pressure reg? if so do what im gonna do and regulate the fuel pressure down til you get there, and whack it back up for what it ran at before

wouldnt drive it on or off boost with higher cc injectors what so ever and no mapping
