Just finish receiving all the parts to basically a stage 1. Hallman pro rx, Blitz inducion cover, Defi bf boost gauge, and Buschur TBE. Installed the Blitz and gotta say that the sound is definatly an improvement. The only complaint is from the shipping of the Buschur TBE. First the packing was very poor, it can with the tip of the muffler dented. Had to take to a muffler shop to have it banged out and still cant install because the bolts were missing (Jarod is sending out a new set). Cant Wait to feel the power with everything installed and tuned this week, should be crazy running 104 octane!!!
