Any feedback is truly appreciated. The longer you've had it installed the better, really like to hear your opinion.
There is a great gain to be had with this system. Here is a dyno sheet from a bone stock ZL1 overlapped with another run 30 minutes apart after installation of the Roto-Fab intake system. Keep in mind this dyno was done with the hood up, but I would expect similar gains coupled with the Big Gulp at freeway speeds.
Please feel free to call, PM or email me anytime with questions.
