Install these, even on a stock car!
Apparently my Solstice GXP had a minor boost leak from the factory cheap screw clamps. Before install the boost gauge would peak and hold about 13psi, now it peaks at 15 and holds 14. Install is a bit tricky if you don't take off the front bumper for easy access to the intercooler connections. I did it with the bumper on but it requires a bit of dexterity and patience. Don't think, buy these!
