Just got a 2018 1500! Buddy is ragging on me for not getting an 8. Need some good starting points for modifications. Any engine tunes worth a crap for the 4.3L? What will the tunes do? Also looking for recommendations on exhaust and intakes. Again, are those mods worth it on a 6?

 

Looking to make the truck a bit more responsive and maybe louder.... not race car loud... just would like it to sound more like a truck. Thanks in advance for any information.

I think Magnaflow makes a nice sounding cat back exhaust for the 4.3. There are videos on Youtube, I could be mistaken on the brand. Get the Airraid MIT and do the air box mod to get a bit more sound out of the intake. Do the "paint stick" mod on your gas pedal and get a throttle controller, I have the one from Soler Performance. It makes the pedal feel way better. Headers aren't worth it unless you boost it.

 

For tuning your best bet is a custom tune from a reputable company. Diablew and Blackbear are popular on here. That will get you a little bit more power. Run E85, or turbo it for the biggest gains

All of these motors respond about the same to the same mods.Bolt ons arent going to do much for power until you open the motors and tune the ecus.If you want a bit more power get an exhaust the shorter the better and run E85 if you can tolerate the 12mpg in city.Jet Performance has some removable piggyback modules that will help a little with faster shifts and Range has some AFM modules that can keep cylinder deactivation from kicking on but thats about all you can really do without tanking your warranty.If dont need a warranty and really want to get serious with power boost is always the right answer

If you want the most out of this engine, you can do all the bolt on mods and then get a tune to get the most out of them. If you find an exhaust you like then headers will make it louder but the performance benefits for headers will probably be minimal. Also exhausts on these trucks can sound good until you get into the higher range of rpms (Highway Speeds).

 

A tune will be your best bet if you're looking for something easy to wake the truck up and companies like Blackbear will retune for free as you add mods.

 

Turbo is not as easy as it seems. Not a lot of support for this engine in that regard. No off the shelf options so it would have to be 100% custom and I haven't seen any reliable power made through a turbo yet on the 4.3 ecotec.

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Wow I'm in a pickle. (Broke down truck) and a story.

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.

      They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years
