Well it takes about 3 minutes to pull that baffle out of that peice of pipe and makes a little difference. Nothing noticable, but you can tell. Also, i just moved my MAF from the airbox to the last peice of rubber tubeing going to the TB. You have your airbox, then bolted to that is your MAF, then a 90 degree elbow which is clamped to that long black pipe (which has the removable baffle inside) then that is clamped to a 45 degree elbow which clamps to the TB. At that 45 is where I put the MAF, and that as well made a little more differance as well. If im going for gold, I have to hit 2nd at 30, 3rd at 57, and 4th around 70. all 5th does is slow me down. The fastest I have ever had that truck is 82 and I got on the freeway, went through the gears like hell, and held my foot the the wood all the way to my next exit which is approx. 7 miles. 82...thats crap. She will scoot around town just fine, but has no power. I attempted to tow my 14' aluminum flat bottom to the river.....I had to finally down shift to 3rd on the freeway! I was doing 43 mph. Ya, Im in the mist of a turbo and or v8 swap.
