Upgrades, emissions, etc.
Ok folks, here's where I'm at. '05 6.0 PSD. I primarily pull a 7500# +/- travel trailer, with a motorcycle in the bed of the truck. I would like to increase cold air intake and open the exhaust up a little with a larger bore exhaust. I have to leave the cat on I think because they inspect for it at emissions testing. I have been thinking about one of the computer chip programmers (ie. Hypertech or ??), but here's where I have the problem. I have no pyrometer, and dont' know whethere I need to worry about that or not. I'm not trying to make a quarter miler, just one that works a little better. Pulls great as it is, just trying to make it work "easier"....if it's possible.
Comments on my train of thought? Products you may have in mind? I really don't have the desire, or the G's for all the bank's upgrades.....unless it's a must....
