IPD Plenum+Intake=CEL HELP

I installed the IPD plenum, TB, and Cold air intake. after driving the car the CEL came on. The code indicated MAF. Changed it and CEL went away and back again with less than 50 miles driven. This is very frustrating. Anyone know what to do? Im away from the car so cant read the codes. my intake filter is a paper filter from injen so its not that. This IPD install has been a pain in the A$$ so far due to the problems I have got from it.

The IPD ...

... and the similar TechnoTorque should not generate a CEL when installed correctly.
You probably have a vacuum leak from a misaligned rubber connector (usually on the bottom where it's not obvious).
There are also vacuum lines and a vacuum check valve that connect to the rubber pieces that sometimes get overlooked.
Recheck all of your work.
Once you find the leak, correct it, the reset the CEL.
Happy Boxstering,
