Hey all, I spoke briefly with a guy at a local performance shop here re trying to unlock more power without breaking the bank. I already have an intake and programmer. I did the muffler delete. I’m honestly not too interested in upgrading the exhaust. Unless I can find one that’s super smooth sounding(doesn’t sound like a tractor). 
 

anyways...he mentioned that I could swap out my gears... does that make any sense? Would it make a noticeable difference? If so, how much would something like this cause and what would a good ratio for city/highway driving?

 

thx in advance

I forgot to mention I’m RWD...not sure if that makes a difference or not..4:10, eh? Does that prioritize low end  acceleration?

have the tuner reprogram the transmission.  stock is horrible. I have zero engine performance parts, but am slowly tuning the A6 trans , and i swear it feels like i added 15hp by reducing slip, tcc poins, TM, an cooling to 135 F

 

gears are great for towing and off the line hole shots and shitty MPG. stock is 3.42, which sux for running 35" tires, but in stock trim its great  for city and highway MPG, and top speeds with stock diameter tires

Ok, sounds good. Would it be worth it to do the rears? I think I can control shift points etc with my programmer. Tbh I’ve never really played around with it. Just set it to 93 octane

I first did tune and trans tune. Wasnt enough for me. Gears was a best hit before a trade to diesel. U have to make tht decision. If u have it i would do it. Especially if u tow.

I don’t tow but I always have tools and stuff in the back and a heavy ass speaker box. I’m guessing about 1000 lbs ish above stock weight very other day or so.

      Ac not keeping up

      By Aimatdeer · Posted

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Welcome back! No, it definitely doesn't pass the sniff test. Even "ceasefire" needs an alternative definition these days.    $5.29 at Kroger today

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
