This morning i finished installing my edelbrock headers(pain in the a$$), and with the extra cash i baught a CAI. The headers made a real improvment in the acceleration of the car. Not only is it faster at higher speeds, but its got a nice rumble and kick to it. I dont see any difference off the line, but at higher RPM's, and faster speeds, the headers really help. My truck would dog a little over 60, but with headers, it picks up fast. I really like them, and my truck feels like it gained really well! I am trying to choose my next mod....i need better off the line power, once i'm rolling there no stopping me, but i can improve off the line. I was thinking of a programmer, because the endless number of settings to choose and tweak. I thought of a Mopar performance PCM, but i cant afford 93 octane at all times. Plus i do tow occationally. Will a programmer help me with my off the line? any other suggestions my sig will tell you my current mods.
