FiTech EFI system

ran fine on carb, I just changed out the intake manifold gasket and tightened the fitech down. I cannot find any vacuum leaks. also tightened down the intake manifold. it's around 2krpm now. I let it run for a few minutes and it dipped below 2k. Maybe t needs to be driven for it to learn?

If I were you, I'd start a new thread and we can help you there in detail.
Once you start that thread, do this:

Go to the 'dashboard' and tell us what it's showing.
List the values for 'MAP', 'TPS', 'Target RPM', 'IAC Steps', 'IAC Learn', 'Run State', and tell us if anything is found under Fault1, Fault2, Fault3, or Fault4.

With those, we can help you troubleshoot - or call FiTech and see if they can help.
