Boss intake manifold and Airaid cold air intake issues

Looking for some help. I installed the boss intake manifold and airaid cold air intake a few months back. On a cold start and drive down the road I get a hiccup when shifting gears at moderate to high speeds. Obviously, more noticeable when I'm going faster. The car lags for a second after shifting and I'm not sure why. I don't get any DTC's and the issue goes away once the car is reasonably warm. Does anyone have an idea as to what the issue may be? I've tried different tunes; an 89 and 93 octane tune through Bama and a 93 octane tune through Lund and I have the same issue with all of them. Hope you guys can help!

I"m no expert for sure--but, it sounds like something is not tight..as the engine warm up it haS to expand and by doing this it gets tighter. I have the Boss manny and Cai and have no problems--check fuel line aNDtb-- hOPE YOU FINE IT SOON

Hmm, this is very odd. I have a 2011 GT with the Boss Manifold and CF Airaid CAI and have absolutely no issues! Your car is going to always feel stronger once it's up to operating temperature, I would not recommend taking the car to high speeds on a cold start.

I'd give the install a once over and make sure everything's good to go with the Throttle body, cuplers, fuel rails etc.. Basically just give the Manifold and CAI install a once over!

Thanks! Well, let me back track a bit. When I originally installed the manifold I didn't install the purge valve correctly. The line from the purge valve to the front of the manifold (by the throttle body) wasn't connected properly. When I tried to disconnect it I broke the whole fitting completely off. I tried to use JB weld, but it didn't hold. So, I got some rubber tape, the tape that sticks to itself, and wrapped it. It's been holding it in place really well, but I'm almost certain that's where my issue lies. I have to check the type of hose I'm using, as well. If I'm not using emissions type hosing, it could be that, too. I'm probably going to buy a whole new manifold and start over. What do you think?

ahh, that makes much more sense. I've seen that fitting brake before and it's definitely tough to fix after that! Unfortunately, you may want to check out a new Manifold or maybe this is an excuse to upgrade to the Cobra Jet manifold.

I wish I could be more help but once something on the manifold is actually broken it may be hard to scrape by without small issues like this.

Do you know where I can find a CAI tube to connect to the Cobra Jet throttle body?

And do you know if Bama will provide a tune if I drop $1,800+ on these new parts?

We're working on both of these things as we speak! As of right now, not many people are running the Cobra Jet so we haven't been able to test it much but we're going to get started on that very soon.

I'll be sure to let you know when we do!
