Hello, I'm looking to buy a Racepak IQ3 dash for my nova and it is 90% a street car, so I for sure need fuel level, volts, etc. Right now the car just has a carbureted big block so I have no need for data logging, but later on down the road I would like to switch to a turbo LS motor, so I will find benefit from the data logging, but that won't be for quite some time. Should I just get the dash with 2 USM modules for all of the stuff I want to display and then upgrade to a data logger later on down the road, or what would you recommend? Please let me know. Thank you.
