your numbers are low from the dyno and the way you dyoed it.. looks like you just floored it at 2k and let it roll.. the dyno jets rollers are to light to spool that big ish turbo especially with to much fuel from your big ish injectors. i bet i smoked like you had the numbers you thought.. if you want better numbers your going to have to drag your brakes at around 1800 hard and make as much boost as you can before 2k before you start the run.. otherwise go to a load dyno.. you will probably still be disapointed that you dont make the numbers you thought you had but it will be better..
