JET or PCM for less???? Need direction.

[ETD]

Going for the PCMforless doohickey myself. Won't be shy to let y'all know if it did nothing, worsened, or, improved things. (BTW, tried to call twice about something, no big deal but, got a voice recording each time - so customer service isn't exemplary if you'd care to know.)

The way I figured was I wanted to spend some money on the truck and the choices were new air-intake, exhaust, or computer software. I didn't really need any data such as dyno because these have really been more for marketing. Have y'all looked at the K& N dyno for example? The RPM that the truck must function in inorder to see a difference is NOT REAL WORLD. So why does it seem to me that people put in new air intake system without batting an eye lid (same with exhaust) as if it should do anything to the truck especially when the OEM setup is ALREADY COLD AIR .
Anyways, what I'm saying, is sometimes decisions to "accessorize" the truck don't have to be logical. How else can you explain all the BLING??
