Installed all new CAC boots and now the truck runs horrible? ?
Got the complete boot kit from riff raff, with plenum inserts and new clamps for boots going to plenum. (Nice products ). Got them all installed and clamped down , went to run the truck this morning and it ran like crap. Was really looking forward to an awesome running truck since old boots were leaking, but now it runs alot worse. Should i keep clamping down?? Afraid im going to bend the aluminum pipes. They are all around 15 lb/ft . Keep cranking or could there be something different to look for. Anything i can look up on obd link mx?? I dont have a boost gauge.

More than likely something is misaligned. Check your spider to turbo connection where the v-band clamp is. You can also pressurize the system and make sure everything was installed correctly.

Yes i have a forscan, just new to this and really not sure at what PIDs to look at for a problem. I also have a leak detector I'm going to try out for the first time. Is it ok to hook up the leak detector before the CCV on air intake

No. If you do that, then you'll be pressurizing the crankcase. You don't want to do that. You must do it after the CCV so you isolate the intake.

Or, you can plug the CCV. I think removing the plumbing to eliminate the CCV is easier.

Ok so i hooked up leak tester and when I pump it up all the air is leaking out of the CCV. I have the leak tester hooked up to the intake pipe after the CCV. Is there supposed to be air coming out of the CCV? Or do I just plug it up??? Please help

From what I remember reading about the test (never done it myself), yes there is to be air coming out of the CCV. Although, take a spray bottle of dish soap and water and spray it where there are joints for the air to escape. Examples are each boot end and turbo to spider connection.
Staring at 3:20 in this video is what you are looking to do in order to find your leak. You have one, you just haven't found it yet.
Then this video provides a good example of how to spray and what to spray.

Are you saying that the pressurized air is coming out of the dog house on the VC?

The inserts were popped into the inside of yhe plenums, with out taking them off. I have sprayed all connections and cant find any leaks. I have pumped up to 20 psi . And leaks down within 8 seconds with all air coming out of ccv. The truck runs but has no pick up, feels like no boost but cant find a leak. Stumped
