as for that pop when you were turning did you find out what that was from???
the sea foam is GOLDEN i put some in about every 40 - 50,000 miles wheather it needs it or not
as for your filter deal, you could get the same results out of putting in a K&N filter and leaving your air cleaner cover flipped over the right way.
the TBI Spacer will help a little with the power but more with the fuel economy, Since it's a 5.7 a flowmaster muffler will help too. Changing out the fuel filter is simple and may be needed also.
Another thing that worked great in my tahoe and made a noticable difference was I put in a set of E3 sparkplugs they added power and helped a tiny bit with the economy also. I don't have a race truck or anything now but it runs really well.
ALways use Mobil 1 and Lucan treatment in everything too, Oil, Transmission, rear end, and power steering. both of those are like gold also for making your vehicle last longer.
Lastly you want to let the truck WARM UP when you first start it up each time before you go driving it. I don't know why but no one wants to take 5 minutes or so to let them warm up properly everyday, they just crank it up and go and the oil hasn't had a chance to circulate properly that way yet.
