Hi all, It was suggested that I add some transmission fluid, after checking my fluid my "cold" level was fine but my "hot" level was low. I added about half a quart and It seems to have improved, albiet I did this a few days ago only, will give updates. Wouldn't think transmission fluid would be on the lower end at 32k miles.

Hello all, I have a 2018 silverado crew cab 5.3 with headers and dyno tune, and the oddest thing happens when i'm turning a corner. it seems to almost be stuck in a high gear after turning a corner and upon accelerating the RPMS actually go down as well as lackluster performance and poor speed... if I jam on the gas pedal it will down shift but at really high RPM which seems completely out of line. Versus after turning a corner, accelerating and the RPM going up and a gradual transition to a higher gear. Please advise, thanks in advance!

HI, I'm supposed to go back this Friday for something else and figured I would bring it up to them at that time, not sure what the cluster and scanner are saying regarding temp. We're in Florida.

Hello all, I had some long tube headers put on my 2018 5.3 silverado with a high flow 160 stat and a "street tune/calibration", the truck ran great without the radiator fans running all the time. This tune/calibration was taken off. I recently got a Dyno tune done to the truck and my radiator fans are running NON STOP. Was this because the technician made a mistake and didn't realize I changed my thermostat, or is it even with a high flow 160 stat the fans now have to run all the time? please advise, thanks a lot!

I appreciate it

Hello all. I have a 2018 silverado with a 5.3 I have American racing headers installed with some Borla dual side exit exhaust, I also changed the manifold to the one for the 6.2 liter, cold air intake etc The problem is it's not calibrated. What device would you recommend to get this properly calibrated ? Thanks in advance!

Hi Lucas and thanks for all the help, I understand If I get a TC i'd have to get my transmission tuned, however if I change the gears to 4.56 would I have to get the transmission tuned? thanks again

HI thanks for the input, I don't know what type of plugs he put in, apparently the plug cables were getting fried by the headers and caused #7 to misfire, as well as a few others not as frequently though, the guy that did my mods suggested I get a new torque converter that would "feel like I lost 800 lbs of weight in the truck"

Thanks for the advice, I'll look into changing the gears.

Hello All, I have a 2018 5.3 silverado, currently have a 6.2 manifold and throttle body, cold air intake, new thermostat, (had high performance plugs until they started misfiring now back to GM), Borla dual exhaust, american racing long tube headers, and a tune. I have a 7" lift with 35" tires. Besides a supercharge or turbo I heard there is not a ton more I can do besides a high performance torque converter. Any suggestions or advice on this would be very much appreciated, thanks in advance.

Thank you!

Considering this seems like a calibration issue with the transmission (as it was "on the road" calibrated) is it possible for this to happen sometimes, and then at other times nothing happens at all? Case in point, I drove it this afternoon at around 25-30 MPH at 1000-2000 RPM in 5th gear and felt the several small "shifts" or "slips" that I normally feel. However, when back on the highway, 65 MPH at around the same RPM 1000-2000, and didn't feel any of the many slips, jerks, I felt just this past saturday at the same speed and RPM's. Is this commonplace with a "modification" like this? Thank you!

I appreciate it

Sorry I meant to say it's slipping at points, not shuddering, and pretty much only in 5th and 6th gear at lower RPM. I was on the highway (maybe 65 mph) at say 1500 to 2000 RPM and had so many point of sudden "slips" for lack of a better term, and had to exit the highway. in gears 1-4 it seems to have no real issues, even at high rpms, and gears 5 to 6 has seemingly no real issues at high rpms for the most part. But when the RPM goes down to say 1500 to 2000 at at a constant speed ( 40mph to 60Mph ) it seems to have the worst points of slippage

Thank you!

Hello all. I have a 2018 Silverado 5.3 with approx 22k miles on it., 6 speed trans. Initially I got a few mods, borla dual exhaust, Afe gt cold air intake, swapped the throttle body and intake manifold for the L86. After this point was running much stronger but lacking in areas. I decided to get the long tube american racing 1-3/4" long tube headers, 3" y pipe with high flow cats, 160 degree thermostat, brisk performance spark plugs. And finally it was calibrated/tuned, really woke her up*** As of just today, the transmission?? seems to be shuttering (for lack of a better word) at highway speeds, and not as drastically upon acceleration and constant speeds. Any advice as to what this may mean, how to fix it is greatly appreciated! Thanks in advance!

I appreciate the advice!, I think i'm going with some american racing long tube headers (with cats) and a calibration ( 1 guy said he does it "on the road" as trucks don't fit well on the dyno), the other guy said he does a full tune with the dyno, ?? thanks again

Thanks about the water heater caps, have no clue about turning on the tables and power enrichment

I appreciate the advice, I've been hearing that shortys don't do a ton and the noise factor can be a problem with longs. They are telling me the long tube stainless works headers are about $2000, with $850 for a tune and dyno and $1000 for labor. What is E85? Would you suggest I do the tune myself, what product would you recommend? Thanks for the help!

I see so the oil is coming in from the Cold air intake to the motor, So put the breathers on the valve cover ports. What about the hoses coming off of the CAI, do I cap those off? Thank you

Hello All, I have a 2018 Silverado with the 5.3, so far I have done these "mods" AFE power momentum GT cold air intake. Borla Dual exhaust Replaced the L83 throttle body and Intake manifold with the L86 (non ported) Have a nice increase in power, I'm thinking about headers now. I've heard a lot about the long tube headers I'm thinking about going all in with the long tube "stainless works", this will require a tune and about $4k total On the flip side I'm thinking of Equal length shorty headers to cut down on some costs and eliminate the need for a tune...? My question is, if I were to get the long tube headers, how does it work with the cats? Is it better to get Cats or no cats? Do I have a choice? Also, If I were to get the shortys, what brands do you suggest? Would it be necessary for a tune with only shortys? Thanks in advance!

I Appreciate all the help! As it sits I'm going for the 6.2 (ported manifold) and the "stock" 6.2 Throttle body I"m not going for the ported throttle body as my mechanic cannot tune it. If you get a ported l86 6.2 manifold, do you have to get a ported throttle body also? Thanks in advance!

I Appreciate all the feedback, I just got the Borla exhaust and next step is the 6.2 intake and throttle body with the tune, I have a 3.5 lift thinking about getting 6.5, would headers be overkill with all these items? Thanks in advance

I appreciate it! so a 6.2 fits fine i'm assuming, any recco's on getting it tuned?
