Well, I don't have the support mods...when I said I didn't have much knock, I meant the PCM was pulling timing, hence the lousy mileage. I could reset the mpg gauge on 15 headed down towards SLC and still only get 25-26mpg, vs 34-35mpg avg on the 3.8 pulley. That's why I was gonna ask if you could help me tune it, I have a completely stock PCM right now...
