hey has anyone sprayed there 2005-06 GT at the track yet? im guess i'm wondering if they had any backfire problems, or if you were using the WOT controller box... im interested in getting the Zex kit even though im not a huge fan of there early products, this system seems well engineered... what are your opinions...

 

i put thier kit on when it first came out and have had no problems. easy install and is clean. the only thing is the horsepower gains are for the flywheel and not tires.
