icen

i know its not a lsx based engine, but i figured yall are the people to talk to. I have 02 trailblazer with the I6, and im thinkin of throwin a 100 shot on it. I already have intake and exhaust, and am pretty much stopped there, because of the lack of aftermarket performance. Wat supporting mods would i need with the 100 shot, upgraded fuel pump (walbro 255lph) and 93 octane? Note that there is no tune availble anywhere besides jetcrap.
