time for a noob beatdown here
first thing- to put down 380 whp on a 2560 setup is just pathetic- k04s are putting down north of 450whp on a conservative tune
the company that sells a 2560 kit is vast- with their fueling and tune puts down 525 whp on a base tune- they are flow rated for north of 600 on that setup
here is what I think is wrong with you- maybe if you had an a4 with an s4 body and a 1.8 with a 2560 you would make 330whp- dual 2560s at 15 psi would still put you over 400whp-
here is a car running 2560s- evilevo- and he runs 595 hp-
if your really running 2560s an x-1 wouldnt even be close enough as it cant house the 86 or 90 mm throttle body along with the fact that your maf has to be repositioned for that kind fo setup. If you actually knew anything you would know your tuner, your hotside size, what type of injectors your running, side mounts, everything
what type of heads does it have, what company is your wideband, and who does your tuning-
now that everyone knows your talking out of your ass please go kill yourself.
