Here is what i want to see. 2 bone stock 1.8Ts (GTis, Jettas, i dont care as long as both are the same car). Same model (as in the same wheels and everything to make sure it is the same weight). Then I want them to both be filled up with the same gas (they can get it together and both have a full tank). Then I want one to get an APR chip and one to get a GIAC, then have them dyno'd on the same day, with the same person in the car. That would be the only REAL way to tell which makes more power.

There are a lot of variables that need to be considered with this, like temperature, what brand dyno it was run on, etc. With how close most of thoose numbers are I dont think it is fair to say one company is better then the other without considering EVERYTHING.
