Sometime down the road I may get headers, rockers, and a 3.6 on it, and will just send the pcm back to Will for a retune, but for now, I have better ways to blow $1000..
At this point, I dont plan on having much done as far as mods.. No headers, rockers, and still on stock 3.8 pulley.. Only "mods" I have now are AL 605s, TG shift kit, 180 stat, and a cone filter off the MAF on the stock rubber tubing for an intake.. Will there be much improvement , if any with getting the PCM? I dont expect much, Just the basic, quicker shifts, deleting of some codes, 180* fan turn on, and higher shift points.. Is that where it ends, or are there any noticeable differences?
