Thats entirely yor choice there. How do you want the car to be set up as? Do you want to do an intercooler like mine? You could do a blow through meter and run a BOV. Or you can do a sucker meter and run a draw though meter. A blow through will give the best results for sure. I personally like the Pro-M meters. I have used PMAS also. It was good but the pro-M is better in my opinion. Then you have SCT meters. With those you HAVE to have a tune to get it running as the meter and fuel injectors go hand in hand. You cant get an SCT calibrated for 60's to start it up whereas you can with the Pro-M and PMAS. Stay away from the C&L meters.
