Tune with larger injectors? Aside from making sure the air/fuel is OK, does the car need to be tuned when going to a larger injector?
If it needs tuning, is it bad to drive the car to the tuner with the new injectors in?

from what ive heard yes...the computer will be dumping in the same amount of fuel for the smaller injectors even though yours would flow much more...this will result in being overly rich at all rpms and if too rich for too long can wash your cylinder walls resulting in the need for a rebuild...get the tune done asap preferably before startup.

auto tap your car.. if you are getting generally negative ltrims b1 and b2 AND you have a wide open air fuel in the high 12's (and the ltrims lock to 0 when at wide open) then you do not need an adjustment for the injectors
it is not likely the above will be the case.. they will not be right and you will need to adjust to pull them there... this can involve the offset table if you cant get the driveability you want through just the ifr table.

They were $500 new and installed a month ago....$300 shipped I think is fair. I am going to have to spend about $650 for my new ones
