Just installed a Vararam and power duct and in 2 miles the check engine light came on, anyone else have this problem? or tips or tricks on how to get the light to go off? Thanks in advance Nick.

I have the VRB2 no power duct. I never had any problems but others have had reported some with the power duct. Pull your DIC codes and post them. Check for air leaks as well. Easy to miss.


pm your phone number and I will try to help!

Need to be driven 50 miles for the engine to get used to more air. Also, as mentioned above, check for leaks.

The Vararam especially with the powerduct changes the transfer function of the MAF. Your best solution is a tune. Do you have a Z06 or an LS1?

I had the same issue. Here is what I found. At the first connection where the filter connects to power duct (front of car) I had tightened it too tights and oblonged the plastic part. Also, check that there is nothing on the MAF screen.
Also, I have this set-up, and I don't have a tune. Just take your time and check for air leaks. That's more than likely your issue.

I never received a CEL with my Vararam. After capturing data of my O2 sensors at WOT, I discovered I was running leaner than I felt safe with. Got a custom tune and the car felt a lot better.
