I'm looking for some help from my Camaro buddys that run a two step to launch the car. My problem is that the car stumbles or boggs down when I try to use it. I started with it set at 2500 rpm and just killed my 60ft times so I tried rasing the rpms. I now have it at 4000 rpm and it still knocks .8 off 60 ft times? What do I need to do to get the car to leave clean when I let off the brake an keep my awesome 60ft? Thanks guys!
