Quick update
-Launched NDS and went in idle/timing mode.
-Timing light is steady on the last notch.
-Timing in NDS is at 20
-Idle is at around 1300 and cannot drop it with the iacv screw. Cannot get the 750rpm...
-Sometimes drop to ~1100 and timing drops to 8 on NDS.
-Pinched the hose and the rpm dropped...

IACV again ?

:(

Why are you set on 750rpm?

My set my car up to idle at 1200rpms. It idles better at 1200rpm, has better oil pressure, better batter voltage, etc.

To set base timing and work from there.
Before I swapped the cams it was set at about 950-1000 and that's were I want it again.

If the NDS timing and your timing light agree, then your base timing is set. Setting the base timing = syncing your actual timing with ECU timing.

Try adjusting your throttle stop and check for vacuum leaks.

Fixed, went for a ride, did few logged pulls with the new cams. Came back home, idle at 750-800 @ 20 timing in NDS and on the crank.
