Chip change w/any injector swap?

[FastRegalWE2]

I have a set of injectors from a Ford 4.6 POLICE car. No matter what size they are do I need a new chip or is it safe to swap up to a certain # before I need a new chip?
Thanks
Jeff

It depends. If you stay within +or- 2 pounds you could probably get away with a stock chip, but I wouldn't chance it. What size are the injectors and what chip are you running?

I have to check on the inj size, not even sure if they are bigger than stock Gn ones. My chip is the old ATR Pit Bull 112 chip
