First thing we did was installed our new 2008 STI UTEC DELTA and hit the dyno again. With no other modifications but the tune and utec the car mad a huge leap in power. With 291whp and 328wtq just by tuning alone . We then added our own custom made down pipe, removed the factory snorkle on the airbox, switched out the plugs for 1 step colder, and added a forge resirc valve and made 316.4whp and 390wtq.

Oh it seems somebody made a video for us so here it is.
I assume you recalibrated the MAP sensor on the UTEC. Otherwise you will be running a bit more boost then the UTEC reads. It is off by about 2-3psi at higher boost as the MAP sensor has changed.

Nice numbers!
