Yeah, a TVS system would work well. There have been good results from a 1900 on 5.3L motors. Not sure if the 2300 is too much blower for the 5.3L... Since the new TVS system has come out--the Radix systems have gone down in price. The Radix is still a good unit which makes good power (+~150rwhp), but you WILL need to invest in a meth kit to keep the IATs down...
