Vacuum (yea, I know...)

[coach36]

I deleted the CMCV /IMRC and EVAP. The engine is running but rough and feel like it ain't perform as it could. I noticed after turning the engine off, that if I unplug a vacuum line from the intake, that there is still a huge vacuum on/in it. It's almost hard to pull the line off. Is that suppose to be this way? If not, then I probably messed the order of vacuum lines.
There are tons of videos out there which instruct on CMCV delete when putting a 2018 intake on Gen2's, but i can't find any for the Gen3. I also know about Edwards post, but it doesn't help me much since he still runs with CMCV.

I hope you can help me on this.
Thanks in advance,

For starters the GEN 3 Coyote needs a tune to run properly. The base tune is good just for starting purposes and short spin to move the car. I have the CMCV functional on mine, as I let Lund tune know its on the motor.

Yep, and mine is off. I need to know about vacuum line order

this may help, I'm trying to get my brain around this as well as I'm doing the IMRC/CMCV delete

That thread doesn't cover the Gen 3, which is different. This post does: https://thefactoryfiveforum.com/showthread.php?26630-Edwardb%92s-Gen-3-Type-65-Coyote-Coupe-59-Build-Complete-and-Graduated&p=351623&viewfull=1#post351623.
