Re: Vacuum pump running
You can do this without removing anything if you want to keep things reversible. Just strap the secondaries open, and make the prom calibration changes for the mod. If the motor is modded, you would likely need to tweak the fueling tables for part throttle and cruise operation.

Half the fun is having a functional Full Power Switch
I have one ZR-1 with secondaries removed and three ZR-1s with secondaries functioning perfectly.
The TRICK to a fun to have secondary system is a vacuum system with no leaks. The TRICK to diagnosing/fixing/having a vacuum system with no leaks is Blocked TB Coolant at the Injector Housings. Eliminated IH Housing and Throttle Body (TB) Coolant system Tricks With TB Coolant blocked you do not need any sealant on the Plenum Gasket and Plenum Removal is essentially a ten minute no mess maintenance function. Removing Plenum (including the 10 minute Plenum Removal) Most Importantly, Removing the Plenum with TB Coolant Blocked will not involve Coolant in any regard (removal or filling Coolant). Once the Plenum is Removed vacuum leaks can easily be found and corrected. Checking for Vacuum Leaks TIPS Having an Operational Secondary Full Power Switch
