It will require rescaling of the IFR table at the least. And a good retune as well, why are you going to 42#s. Were the other mods to require this? If so a new tune will be a must.

Need a bit more info here

if your tune was done correctly, you can swap the injector constants, and everything will work as well as it does now.

if your tune was done by a hackjob tuner that screwed with injector CONSTANTS in a attempt to tune your car, then you're fugged and you'll need to have the car tuned all over again.

if you're still on the stock tune, it was done correctly, and you should just have to change the injector constants.

The car has a h/c with a F13 cam that was installed and tuned by Futral with the stock injectors. I have since aquired HP tuners and smoothed the PE but done nothing else. The car was low on power and have since found that I have destroyed the #7 piston and had severe leak down on most of the rest. Replacing the pistons and keeping everything else the same except changing the headers from TPIS 13/4 to Kooks stepped.
Thanks
