As stated. I searched and found pages and pages of tuner info. Here is the scoop. I have a relatively stock 5.3. Cat-back exhaust, catch can, High capacity stock air filter, PML diff cover.... see sig for complete list. I'm looking at buying a large 29' boat next year and have been modifying the truck for more "towing" if anything. Not interested in lifting, leveling or drag racing. I looked at buying a '15+ 6.2 max trailer pack version of my truck yesterday and I'm going to take a bath being my truck is only 21 months old and I have 45k on it. I drive my truck a lot of work and personal use. That's the background. With that being said I'm tossing the idea around of a canned tuner. I'm not interested in turning a tuner into a science project or getting the one that gets every HP. I want reliability for towing and business driving. Just wondering if I could get a bit more HP/torque out of my 5.3 to hold me over for another 2yrs or so until I'm on the market for a new truck (when it makes more sense) and I'll end up buying a 6.2 max trailer pack then. So help me out here guys....

 

 

 

This seems to be the way I'm leaning:

For towing, depending on the weight involved, I'd look into a set of LT tires as well as airbags/helper springs. I have no performance mods and have towed over 8 with my 5.3L CC 3.42. The difference between towing significant weights without LT tired and suspension help is night and day. Hands down airbags and better tires made towing a significantly more comfortable proposition. Standard disclaimer thought.... If the weight of boat suggests a weight distributing hitch it would be a good idea to follow that recommendation.

Panik- I have 45k on the OEM SRA's. I have 7/32" left. In about 12-14 months when I'm boat shopping I'm sure I'll be ready for tires and I am going with LT275/65R18 GY All terrain Kevlar in load range C. Weight distributing hitch is a must for me for the size boat I'm looking at. WD Hitch, Tekansha P3 brake controller and a tripple axle aluminum trailer with E/H brakes my friend. If I'm towing a 29' boat with twin V8 engines I'm taking all precautions possible. I'll be around 9,200-9,800 # on the trailer. My truck is rated for 9,600... with the above items I should be safe as long as I don't drive through the mountains, FL has none, or drive like a jerk. I'm also thinking of swapping out to the NHT max trailer pkg rear leafs. They're not very expensive.

Sounds like you have things well thought out. I wish I could give you some recommendations on tuning. I haven't taken that step yet... not sure if I will. Personally I would go with the airbags instead of the NHT leafs, they will give you more flexibility in tuning ride characteristics vs loaded weight. On the downside though you do have to put air in them on occasion to maintain minimum pressure.

 

LOL..... FL has some rolling "hills" if you head out towards Ocala. I spent most of my life in Tampa up until about 4 years ago.

Yes, I'm located in Tampa. North FL has rolling hills... nothing crazy. My point is I'm not trying to tow this 29' baja outlaw down or up the ike gauntlet. The more I've been looking at tuners the less I want one. Just seems like a headache. I might do a Kooks Catted Y-pipe to compliment my cat-back and the HP mods done. The airbags might be the way to go. I didn't even think about that option. I've never messed around with them. What kit did you do?

      Clunk when putting truck into drive and reverse.

      I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
