[QUOTE="Dan_Goodwin, post: 740667, member: 4960"] I have a 2003 Silverado with an LM7 5.3 on 285s, so essentially the same truck. I had 285s on 3.43 gears and it was indeed a pig, so I swapped to 4.10 gears via a 14bsf swap and it was a noticeable difference. What made a night and day difference was doing a tune ,getting rid of the torque management and getting the transmission shift points dialed in. I went with Blackbear and have been pleased with the results over the last 100k+ miles. You're on the right track to tune it first and gear it later. On an unrelated note, does your trailer have a tailgate? [/QUOTE]
