I know everybody thinks my set ups are different than the strip, but the really aren't by much. I've learned the hard way the harder you hit the suspension the harder it is to make the vehicle go forward instead of down. The one thing you do not want is to hit the tires so hard you kill the shock, lift the front end then the front fall right back down and unload the rear, then finally settle down and take off.
Like above, every vehicle is different, becuase of weight, hp, gears, springs, shocks. and so on. Don't be scared to leave at a lower RPM. I leave between 3,600 and 4,000, sometimes even as low as 3,200. Almost always anything above 4,200 I slow down a tenth on my 60' times.
When guys at the track ask me what I leave at I always tell 'em 5,400 :wink: .
