05 Hammer did not have cats in it, and so they did not need the fuel cut strategy; to keep them clean. Gets rid of the wandering missfire at idle, and the cracking on shifts, decell, etc
Neither did my 07. I have an autotuner anyway. The Deceleration Fuel Cut Off is the only thing I'm wondering about for newer models versus 07 and older.
2007 Hammer, lowered, Bassani 2:1(updated), torque tubes, Dobeck AFR+.
2000 Firebird Formula, 6.0L, LS3 heads, etc, etc, etc, - SOLD
