WELL they are blue so it will make you go faster
Again WNC SPEED has no clue whats going on.........Still cant get the Cobalt SS tuned in even after having it for almost 12 HOURS.
WNC even called Intense Racing in Ohio, which are the people who made the Pcm, and tryed to get them to tell them how to fix it.
AND Intense call Brandon and told him that those guys at WNC are idiots and should not be tuning cars.................Hell they ripped me and Spooky-4 a new one when we went and dyno. 75.00 for 3 pulls with A/F reading. and then they still didnt give us A/F and didnt give us corrected HP AND TQ NO's.

The guy doing it was not the owner and although he was nice he acted like he was in a hurry and didnt want to be there.
HMM I wont go back.
