Yes you can use it, you'll just need to redial in your maf transfer in your tune to make sure your AFR is right.
When the car is being tuned properly, then the sample tube becomes the flow range calibration of the MAF and really has nothing to do with injector size etc, because injector size is specified else where in the tune.
For instance, because I tune my own car, I'm running 60# injectors but I am still using a purple sample tube in my 76mm MAF because I have not exceeded the flow range the purple tube gives me even though I am up there at around 4.5 volts. Once I get close to 4.7 then its time for me to go to the next sample tube size, which will increase the range of the MAF so to speak, but at the cost of losing some bottom resolution for tuning in part throttle and idle.
