I am would like to know if the MAF should be upgraded after installing a new ECM? Any HP benefit?

Does the ignition system need any modification? Such as wires, hotter plugs, or coils?

- Gas Prices

  When it comes to gas prices it seems the rules have changed. My last trip to Oklahoma gas was cheaper than my area in Texas. Between Saturday and today it’s went up 20 cents at my local Kroger’s that’s one of highest per gallon. It’s usually the opposite. Sunday my local QT was 3.19. The price per barrel doesn’t seem to matter much. We’ve seen the profits of the oil companies lately. They’re slow to adjust one way, very quick the other.

  AAA has long kept tabs on gas prices so I'd consider it generally credible. This shows average by state so we have to assume there's some regional variations over/under inside of the states that contribute to those averages.

  Great project. I had the same idea and had also removed (well the trail helped) my lower plastic airdams. Just last week I had a local weld shop modify a receiver cross bar to tuck up tight to bumper. To avoid a few things, they made it protrude out more than I like, but still happy. I only have the plastic factory skid plate underneath. Did remove the frame “cups” and the recovery hooks to make room.

  At least on my 24 with the 10L1000 the dash display for trans temp exactly matches what my OBD2 monitor shows. Unfortunately the same cannot be said for coolant temp, the dash gauge is essentially an idiot light at this point.
