afm dod delete 2015 silverado needs a hug
Richard Latino posted a topic in Troubleshooting & Recalls
Truck has dod delete with stage 3 cams and no more cats as well as being dyno tuned and programmed by the company that did the work on the heads. I've put about 30000 miles on the truck since all that work and other than struggling to get over 13 miles to the gallon I've loved every mile of it. It's been tuned to have 93 octane fuel as well as octane boost in each tank. I have done exactly that and the big crew cab, 4wd, 6 inches of lift with 35×12.50r20s would get up and go and not stop unless you get scared. But then someone puts 83 octane in and all hell brakes loose. Even after 4 full tanks of 93 octane and boost the truck lacked power and when in higher gears at low rpm is is extremely jerky when you accelerate. It also started getting stuck in 3 or 4th gear and the check engine light was #5 transmission solenoid stuck open. After clearing the code ot would shift normally. It has come back on twice but each time I just unplugged the battery for a couple minutes and the light reset and it shifts regularly again. I changed plugs and wires and mass airflow but no change. Where do I go from here? -

Ok first I want to apologise if this thread has been done. I just started my account today. So I bought a 2016 Silverado 1500 LT Z71 4x4 with 37k miles a few days ago. It has a 5 or 6 in RC lift and 35x12.50r20 MasterCraft courser MXT tires on it. And the Hostile predator wheels. My question is, I don't know if the truck has been geared. Tuned. Or calibrated by the previous owner. The dealership doesn't know. The truck doesn't feel "sluggish" to me personally. I drive past the digital speed trap in my town and if I'm doing 30 on my guages the reader says 31-32... On the highway at 70mph my tach reads the notch under 2k.. so 1800?.. when cruising at 30-35 my tach reads around 1100-1200. I find I get in town with A LOT of stopping and going around 13mpg and that's driving very conscious. I notice it shifts around 2500 and then lower in the higher gears like 2000 then 1500.. but seems to chug along nicely around that 1200 mark. Also. My V4 mode has never turned on once. Not sure if that's due to the current cold northern Ohio climate right now. Or if the previous owner has a tune on it and disabled that feature. I just don't want to spend the money on a tune and calibration if I don't have to. When I floor it it gets up and goes fast imo. I don't floor it often at all. It doesn't pull or tow or haul much. I'm a maintenance engineer in a flat Ohio town of 50k ppl. So I don't think I'll regear because it won't be working too hard. If I could get some folks to shed some light on my curiosity I would greatly appreciate it. If all else fails. I'm buying a good tuner I guess... Thanks guys. -
My warranty recently expired on my 2015 Chevy Silverado 1500 5.3L and I was wondering if anyone could recommend a tuner for my year truck. I drive about a 100 miles a day at time and would like to get a little more mpg. I have access to 93 in my area as well. Any help is appreciated.

I’m looking for a tuner or some sort that will provide me with some additional live data. Not really looking for a tune since I have a powertrain warranty through the dealer I bought from. Unless I can tune it and return it back to factory without the ecm registering that there was a tune on the truck.

So I'm not sure if related to my tuner but reading through a lot of other posts and nobody has actually found an answer. My truck is tuned for my 35" tall tires so that the speedometer is correct. Anyways here is whats going on, I can set cruise control at 67mph, bump it up to 85mph but even if I bump it up to 68 once it hits 68mph it cancels cruise control. At 67mph it will stay on. Has anyone found a fix? Do I need to get rid of the tune and put an inline correction for the speedo? As I said, I'm tuned with a bullydog at 34.8inch tires, not sure if this problem was before or after the tune.

Hi Guys. John here with a 2014 gmc sierra 5.3L. I just got my hptuners gear in the mail. I loaded everything up and I didnt realize the complexity would be so intense. I want to tune for elimination of emissions and hp gains, improved throttle response, and anything else restricting the hp of this motor. I am very fluent with a laptop as I program PLCs invthe industry so taking this on is right up my ally. Any help would be greatly appreciated

Found out I need to replace my fuel system control module In my 2009 GMC Sierra 1500 , I bought the truck which has a after market turbo charger in it but if there is a tune on the truck and the FSCM needs to be programmed to the vin number will it still work properly if I install a new one like that ? Or will I need to get the new fuel module programmed differently ? I also am under the idea that it may be the reason the last one went anyway -
I just rolled over 30k miles on my cc4wd, '16 with the 5.3, and 8 speed. I have read more than a handful of people recommending getting a tune (usually when the warranty runs out)...so this is my first post about that...before I really start my research, I wanted to get some real life experiences and expectations... I get that i can make my truck run like a banshee...but I don't need a hot rod...I just want to get optimal power and optimal MPG under normal driving...I rarely tow anything...and I drive pretty conservatively... in my scenario...would you still recommend a tune? what can I expect to get out of one? is there any that are the best value, what about getting a tune off the shelf verses going to a shop and getting it done? if I lose any mpg's it probably wouldnt be worth it...so I need to at least stay the same or improve...so keep that in mind... any insight and opinions would be appreciated!

I Purchased my 2015 silverado z71 crew cab a couple months ago, so far i love the truck accept for one issue that shows itself every once in a while. USUALLY while turning and acceleration lightly at the same time ( lugging the motor pretty much) ill get a very noticable shudder right before the truck FINALLY decides to downshift. Has anyone had a similar issue. Im going to drives my buddies sierra tomorrow and see if i get the same shudder. I have 3600 miles on this truck so i dont think its anything to do with the "adaptive" transmission learning cycle. Ive heard a custom tune can resolve issues but i really hate to do that on this new of a truck, nor do i have anywhere within 400 miles to get it done. New to the forum guys, hope to get some responses, this is my first GM product. Switched from a 2008 tundra with 245000 trouble free miles. Hope i dont regret this purchase -
