I am currently running a dry set up with a NOS progressive controller. I use 2 cheater nitrous solenoids and a shark Nozzle with a .063 jet. The last few times at the track I have been having the problem of the car falling flat on its face about the time the controller should be hitting 100%.

It launches hard..1.55 60' with the controller set at 30% off the line, it continues to pull hard until it just quits. It feels like a wet nitrous shot with no juice, just the fuel.

Anny suggestion on where I should start looking?

 

Under the hood.

 

make sure you got the controller hooked up properly, take it off and drive the car and hit the juice at 100% only, see if it still falls flat
