Will an LS2 ECM adjust enough for 60lb/hr injectors on a 42lb/hr tune? I'm just waiting on my Maggie 122 to get here and I'll be putting it in. It's coming with 42lb/hr injectors but I ordered some 60's for it. I currently have 42's installed with my 112, so (obviously) my car is not tuned for the 60lb/hr injectors.
Originally I was going to just install the 122 with the 42's just to be able to start the car and drive it to be tuned and just switch the injectors at the shop. I was also going to see if i could monkey around with my Diablosport to adjust for the larger injectors, but I was told yesterday from a local tuner that my ECM will compensate and start pulling enough fuel as soon as the o2's see how rich it's running. Then that way I'd be able to drive it to the dyno on the 60's. I was worried the amount of extra fuel might wash out the rings, but I was told that if I ran it for about a 20min drive after warm up it should be fine?
Does that sound about right?

I wouldn't do it. Swap when you get there

Darn. Not the answer I was hoping for. Changing the injectors with the Maggie installed is going to be a bit of a pain because the bypass canister gets in the way.
I've never used my Predator so I'll have to leaf through the manual and see if I can figure out how to pull some fuel out. Maybe it's finally time to add that wideband that I've always been meaning to, but keep putting off.
