Major MPG improvements on my side. In the 2 years i have had the truck i was not even close to being able to get the MPG's i get now. My gapping was out to lunch they were all at 0.044 and up. I get very good MPG now and i am not even trying. Anyways, now i am thinking i do not want to get the new CAC TSB because i am reading horror stories on it and i finally got the truck running perfectly, i love it now. I wonder if they could just change the CAC and not do the reprogram of the ECU. I will ask the dealer if it is possible.

I really think it's all in how you drive. The computer adjusts to your habits. I can drive aggressively and have great response but if I drive moderately for a while it seems sluggish.
Maybe it's just me?

What horror stories? I know some had reported slightly less power feeling but it came back for many. Many of us seemed to have better response and power after the TSB.

I just turned over 15,000 and got a chance to checked my plugs today. I was surprised that every single one of them were gapped at 0.32. Took some relief off because of reading all the threads on spark plug issues.
