Limitations: Transmission and motor. Car was very solid here at this level. It is very difficult to not sit on the limiter in 1st gear with this type of power in the a 5EAT that has some mileage on it. They get a bit sloppy in between gears and hang. You must modify the drive by wire towards redline to get these cars to shift. A valvebody upgrade is recommended and also a transmission cooler. On the DD dyno the converter will unlock/lock mid pull so it's a bit difficult to tune on the dyno. They usually will slip a bit around 5000 each pull.

 

I am a big fan of this turbo, it moves a lot of G/S for it's size. It is decently expensive for an off branded turbo. Time will tell but this is the 3rd one I've done. The 5spd LGT made 350whp/400wtq.
