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. http://www.youtube.com/watch?v=QGkjCDKTzog
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.
