I'm going to run in the searing heat and pi$$ myself off about what my truck will probably (not) run. I put Denso IT-22's in a couple weeks ago, so we'll see.

I have noticed since the last time, that in this heat our trucks pull timing, and I mean like two degrees. That's alot of power left on the table when you combine it with the crap air quality.

So, I added the timing back in so that I have my 16 degrees back again regardless of this heat. I always run with full weight. I'll settle for 106-107 MPH figuring that it will be close to 110 when it cools off again.
