Blow Thru Meter ....Help

I've got 30's in my car now with a blow thru Pro-M setup and I just purchased some 42's and a Pro-m but the meter is calibrated for N/A.....I have a turbo car. Can I use it?.......and does anyone know the calibrations differences? I know the best thing is to get it correctly calibrated, but for time being will it be OK......Thanks

You don't mention anything about the calibration of the new meter, just that the other meter was used on a car with 30's in it. This is the main issue you need to address, making sure it is cal'd to 42's, or another tuning device that fixes this incorrect MAF transfer function.

I have seen N/A meters used a blow-through (think LMAF). The biggest key to running a MAF vehicle in draw or blow-through period is having as much straight, same diameter tubing/piping with no bends or kinks of any kind for as long of a distance as possible before the meter and at least a few inches afterwards.

If I recall, people who use tweecer say get a N/A meter. It has 15% more left before it pegs than another meter. I would think you would be after a tune. But without a tune I would not be sure.
