the difference?

With the current information it is difficult to come to a definitive conclusion. When Technosquare did the original test of the G3 on an automatic, it actually lost hp in the low and midrange and gained a little on the high end. This test was done with the front bumper on and when they removed it they showed a gain over most of the range. Later they did a test on a manual and they showed some gains with the bumper on and more with the bumper off. Others on this board show good gains with the bumper on.
I think one thing is definite - if you perform the Modshack vent modification you will measure gains regardless which intake you are using. This mod really forces cool air into the intake. One other thought - I really think that there is no way valid way to test most modifications on these cars even on a dyno. When you deal with heat soak, trying to guess how long the ecu takes to fully register the changes, and not being able to create flowing air into the engine, the results will always be suspect.
