Best bet is to install it, reset the PCM, start it and let it idle for a few minutes and take it for a very light drive. Do that for a little while, and then drive it like you stole it.
same question about the photos for you! first one to receive it please take lots of pics of the TB not on the truck!

I would like to know if this throttle body mod will actually increase HP? As for drag racing? Did someone say something about loosing low end torque? I am very intrested if this would give me a little more in the 1/4 mile. BTW, what is the bore size difference stock to hipotekon the 3.7L? ??/65.5mm.

There are no dyno charts that I know of for the 3.7l, however F&B has a dyno chart on their website for a 4.7l Dakota with some bolt ons (including a 72mm throttle body) and a performance chip adding 13 or 14 rwhp at the 3-4k RPM range.
