I love my GEN 3 intake, I installed it myself and DIDN'T need to take off the bumper or use a dremmel tool.
Very easy

 

As you open the exhaust/headers up to maximum flow, you will push the limits of the stock ECU and hit the wall with the lean condition, which is easily fixed with tuning.

We have decided not to not produce test pipes at this point, but doesn't surprise me it's coming into the same conditions as with headers and HFCs with the same intake setup. When you get to the full bolt-on stage, you will need some tuning to adapt for the changes being made.

We'll have some options soon direct.. but that's under the R&D blanket for now..
