Hello guys! Well, I have a Cobalt, and i went ahead and gave this a shot. Well, I am not sure it worked. Any advice? I am HPtuned, and have my Desired Air Load tables set up very aggressively, so it could just be that I did not feel it. Now, I have only taken it on about a 5 mile test run since i did it.
Let's see if I understand this correctly, the biggest place i should feel this is between shifts, right? I didn't push it too hard today because I was looking for faster spool. Definitely didn't see that, so I will look harder tomorrow for the increase in boost during shifts. Also, this was a bit confusing as the Balt is setup differently, lol. One of the vacuum lines runs under the intake mani, does a loop, and goes into the mani, kinda goofy IMO.
Most that have performed any kind of tune to thier vehicle have reversed this mod and gone back to the stock set. If you didn't feel a difference, I would say it didn't do you any good. Your choice to keep it or not.
