Same with Gary and a few others (Pete, myself and even you as well in the past 
) as well. 
I used to be an 'ET chaser ONLY' kinda guy back in the day until I tried pro tree index racing and caught that bug.
Nowadays, I'm more likely to just take the roof off and cruise a bit LOL.

No! on my everyday stock tune, i never change my tune, only what the pcm does from the maf, a higher BP produces more power a lower dew point produces more power and better traction. I will take a 30.50 12 dewpoint at 55 degrees any day over 40 29.99BP nd 34 dewpoint even if the DA was within a 400 ft

Seems ET chasing is how a lot of us got started. But some (Pete and I) got more hooked than others on index/bracket stuff to the point that it becomes all consuming.

Yes I'd like to see that also as I have a "TAG" weather station that will predict my ET based on the "corrected Alt" (It needs 4 runs in the data base to start predicting ET's..
I will take the Temp. Humidity, & Barometer & give me a Corrected Alt. When I race I just put it in the shade for about 10 min for it to get the correct readings, & it will predict my ET within .03 EVERY time unless I spin the tires etc...
I can use the Corrected Alt. that it gets from its built in Thermometer, and it gets the Baro. & Humidity also... OR
I can enter the readings if I want so give me the 3 readings & I can give you the corrected Alt. you are racing at...

How reliable are the predictions from that weather station?

Its only as good as the info you put into it.. but mine will predict my ET within .02 EVERY TIME unless I spin the tires...
After you/I get a data base of say 5+ runs, then when I enter a run it will tell me how much FASTER or SLOWER I ran compared to what it thinks I should have run...
What it actually does is take all the runs you enter in it, and take all the ET's and average them out (it bases its ET prediction on the weather...Temp, Barometer, Humidity, that I enter at the time of the run)

Your car will only remove timing on hot days when you let it heat soak. And only then if the IAT/Timing table is stock.
Most performance tunes will reset that table. Most car that race have a good cold air intake. And most of us open the hood between runs.
Better air makes power. If you log the right parameters during a run, the data will tell you. You get more cylinder fill. The MAF measures more airflow. It's really pretty cool.

it ran cooler with the stock, its the 160 stat plus the Cartek fan module, it turns the fans on 100% at 181 and will take it down to 174 and shut off, its been on my car since a couple months old and no fan problems, or connection problems. I have no fan switch or water pump switch, most the time i run with cardboard covering the radiator
