I installed my Arrington supercharger kit with the Magnuson supercharger with Cervinis shaker kit and I am impressed with the power but I live in Colorado and I am having major issues with coming down out of altitude. Going up it operates just fine if I drop as little as 1000 feet the car looses power and wont turn over 3000 rpm major loss of power, stumbles and back fires. I have discovered that shutting it off and restarting it wont cure it, removing the battery terminals + &- and re attaching wont cure it I must disconnect the battery for 45 minutes then it works great until I drop again in altitude. This occurs every time and it doesn't matter what altitude I start from. Arrington has been supportive and says they are working on it but I am losing faith. Has anyone experienced this? Arrington stated I am not the only one in Colorado with this issue.
