You can put larger turbo's in without any problem's.. I have stage 1 remap, 200 cell cat a ss exhaust all done by Badger5, the 190T has 2 side mounted IC's which i was told by Bill (badger5) that the 2 side mount's would need to be bined if i want bigger gain's.. I will have Bill make me a custom front mount in time. You also could uprate the Injectors when going stage2.
