Say for instance I have a Pro M meter that's calibrated for 24# injectors and I want to use 42# injectors. Can a tuner make that combo work via SCT chip?

I finally talked to my tuner today and he confirmed that it can be done. I asked him for a temp tune and he told me sure, but told me that if I drive it easy and leave the MAF unplugged that it will make it just fine, he said it will run in "speed density" mode. I trust him so I'm going to do it. It's a good ways away so I hope I can at least drive 50 or so MPH or it'll take me a year to get there.
I wanted to update this thread. While getting tuned it turns out that since there was such a huge margin between the calibration and the actual size of the injectors, the meter ended up pegging at about 8-9 psi of boost. I ended up having to install a MAFia right there on the dyno in order to tune the car. The cost of the MAFia was about the same as a new meter would have been and the tuner said it serve me well with future upgrades ie more boost.
I do have an issue when I go from load to part throttle where the car feels like it bucks ever so slightly. Doesn't do it all the time and it's not severe. It's less noticeable if I'm at low RPM in 4th or 5th gear. Could this be caused by the MAFia?
I'd hate to think I spent 175 bucks on this MAFia and it be useless. I could have easily bought a lightning meter for the price I paid for the MAFia.
That's exactly what it's doing. I said it was "less" noticeable at low rpm in a higher gear. Say I'm driving at 65mph on the highway. When I level off the pedal to cruise I can feel the car jerking slightly. And I do get popping out the exhaust during deceleration. I told my tuner of this and he said he'll fix it next time I'm in the neighborhood.
With my last supercharged car (95 GT) I used an 80mm Pro M that was cal'd for the 42's and it drove perfect! I did some searching around and it seems like Don95Vert likes the MAFia and says it can be tuned to drive like stock in the right hands.
