i am switching to TPI set up from carb(non computer, non emissions controlled) can i still use aftermarket guages with the new set up?

i have autometers... tach, speedo, temp, oil, fuel, battery.

or do i have to use the stock set up?

 

Only problem might be the speedo. The ECM on TPI models looks for pulses from the VSS sender which on mechanical speedometers is located in the speedometer head. These pulses are sent to the VSS buffer module and then to the ECM. They control TCC lockup(auto trans only) and EGR operation. If the ECM and new setup is stock you will trigger an SES light without the VSS input.
