Thanks everyone for all of your comments. I tried disconnecting the battery for the entire night and when I hooked it back up the next morning, I still felt no difference. I guess i'll have to get a tuner and turn off the torque management. The other issue is that my stock tires suck!! I can spit in front of them and spin them without wanting to. But, on dry pavement, it just gets left by most cars. Lets hope the Diablosport wakes it up. I haven't decided whether to spend the extra money and get the Diablew Tune with it or not since I have no real mods. I appreciate everyone's opinions, posts, and time. Any opinion on shorty headers since all I ever really do is local city driving so I don't need the long tube headers. The shorties will help my low end torque which is all I really need since i'm not racing and the only time I hit the higher rpms as I'm waiting for it to decide to actually go. Any thoughts on that part??
Hey everyone! I've been around and quiet for a while. I have a 2016 Silverado LT Crew Cab Short bed with a 5.3L. I put an Airaid intake tube in it and took out the muffler and just put a straight pipe in it's place. Everything else is stock. Is it just me or does this engine just have no power/torque at all??? I am pretty sure the only reason that I can spin the tires is if it rains and because the stock tires are absolute crap!! I'm definitely considering the Diablosport tuner but haven't gotten just yet. I just have not had a stock V8 engine (since my 88 K2500 with a 5.0L TBI) that has been so slow and had no power to it. I am very much into performance and I know the usual intake/exhaust/tuner tricks, but this truck needs some serious help in the power department in my opinion. Like, in order to get some real power i'm going to have to replace the 3.42 with 3.73 and consider adding a supercharger to get even close to the ballpark of what a V8 engine should have. Am I wrong???
I have been following performance magazines and I'm an ex certified mechanic. Use AC Delco plugs exactly what came I. The truck. The only time they should be changed to something different is if you are adding nitrous, a supercharger, a turbocharger, or decking the heads to I crease compression. Otherwise, the stick plugs made by the manufacturer that they came from the factory with will always perform the best. It has been proven many times having more electrodes to have spark jump the gap to doesn't help. Even with MSD it will only fire to one electrode at a time so the others are useless until the others burn out. Save your money and go with AC Delco!!
I totally agree with Jsdirt! The downstreams are useless unless the cat is clogged. I can't remember off the top of my head but does that engine have a MAP or MAF sensor?? Either of those could be clogged/dirty. Also, have the vacuum hoses ever been replaced as dry rotted vacuum hoses cause all sorts of issues. You can also take a bottle of throttle body/carb cleaner and with the engine running spray around as many gaskets as possible to see if any of them are leaking. A stumble or fast rev of the engine will tell you if the gasket is leaking. Clogged fuel filter or dirty throttle body/throttle position sensor will cause that issue as well.
I have the same color Chevy Silverado and I think the truck looks great as is. If anything do take an inch out of the bilstein shocks in the front but you may notice some steering issues with the rake. Sent from my XT1565 using Tapatalk
What about replacing the throttle body gasket or check the runners in the intake? If the runners in the intake are all carboned up (like an egr does) that could cause it. Or warped heads at those cylinders or even a cracked block? Sent from my XT1565 using Tapatalk
I'm out in Huntley, but i work in St Charles and i'm looking for some fun and maybe eventully some mudding. I would love to get together with some of you guys and have some beers and work on the trucks or just sit and chill with our significant others and have a good time. Any thoughts or possibilities?? Obviously it would be nice for the weather to figure its mind up!
My name is Todd and i'm new to the forum but i'm far from new to performance or trucking or being an auto mechanic. I've been working on cars and trucks for many years read and worked on many performance vehicles and have a professional mechanics background. I hope to learn as much from you as I can help tell you from a mechanic's background and professional training and experience. I live in Huntley, IL which is a far northwest suburb of Chicago and I just bought a 2016 Chevy Silverado 1500 LT with a 5.3 L Ecotec 3. I'll post pictures of it shortly. It's a Deep Ocean Blue Crew Cab.
Blueballs replied to Zane's topic in The GarageI'm new to this forum, but i'm far from new to Chevy trucks or performance mods. I am a professionally trained mechanic and have worked on many different manufacturers as one and there is not now nor will there ever be a perfect way to measure gas mileage. The human factor is now and always will be the 1 factor that can't be made perfect. We all drive in different types of traffic, with different styles of driving, and different amounts of love for pure horsepower and speed. The distributor of the product has made it clear that there is a POSSIBILITY that you could see gains up to 3 MPG. Leave it at that and don't even bother arguing it because there very well could be the possibility of gaining that much from this intake. What you will most likely notice is that your truck reacts faster to when you push the gas pedal. This is because the intake has streamlined the air to your throttle body and smoothed it out quite a bit over GM's original design. This design looks great and looks like it would perform quite well (this is said without owning one but having owned many other styles just like it). The only thing that i'm not happy about is the fact that it has a K&N OILED filter on it. I've had them for years and just recently started doing more and more research on them, and from the results that I have seen and found, I don't ever want another. Oil attracts dirt, dirt on the filter means less air is getting through to the engine. Less air in the engine means less horsepower. Less horsepower means that i'm going to be mad and extremely disappointed. K&N air filters will clog up faster and once they start to get dirty very quickly start performing worse than a dirty stock air filter. Soooo..(now that that rant is over and done with) my only wish on this design (other than not spending that much money) is that they would offer a dry air filter option with this intake. If you could offer me the option of a dry filter at a slightly reduced cost, I would really consider purchasing this product for my 2016 Silverado 1500.
