2013 Terrain timing chain, need some advice.

I just replaced the timing chain, tensioner on my girlfriends terrain. Did everything by the book. Went surprisingly too well and started up, runs great. Now we got on the highway tonight and punched it a bit, sounds like it’s got a intake leak, as if it were to have a cold air. Just noisy now and wasn’t there before. Could this be timing too retarded or advanced? Runs great though, no misses or surging. Anyone had this happen?

Not enough info here, is the vehicle a 2.4L or V-6.
The 2.4L has 2 chains and the V-6 has 3 chains, were all replaced with new giudes?
If the 2.4L you may have a problem with the exhaust manifold.
Did you check for trouble codes?

You talk of a timing issue, when installing new chains you count the links between the gears, as a double check, so you are sure the chains are on correctly.
Lots of possible places to go wrong.

It’s the 2.4L All guides replaced, I didn’t do the chain for the water pump. I’m guessing that’s what it is anyway. I just did the main timing chain. No trouble codes ran.

Any problems before the chain swap? I'm wondering if the catalytic converter is getting plugged?

Nothing like that before the chain swap. The upper guide was chattering as the plastic broke off due to chain being loose, reason for the chain swap.
