Vararam Power Duct and lean codes.

This seems to be very common. I have an 01 that I put the power duct, blackwing, and exhaust the same weekend, and since then it is getting lean codes. I have read many posts saying check for loose connections. I have done that and gone through the install again retightening everything again. Still gets codes even on short drives or just letting it idle. One thing I did notice is that my MAF does not have a screen that some people say helps. I'm going to to switch back to the stock duct and see if that helps. Any other tips if doesn't work. If it does work I'll leave it off until I do headers and get a tune.

Putting the stock one back on seems to fix it. I'll know for sure by tomorrow night, but idling in the garage for 10 minutes with the stock bridge back on and no codes.

I got a re-tune after the vararam, fixed the problem permanently.
