    It appears you are correct. I don't have access to the truck I'm tuning until next weekend, but I did indeed pull the FSCM the first time. Thank you for the response.
  2. 2011 Silverado I just licensed yesterday shows "Unlicensed"

    Yesterday I did a full read and pulled the stock file from my buddy's 2011 Silverado 5.3L/6A. I brought it in my house, did a "Save As" which asked me to license it. I bought 2 new credits, spent...

    I did see that the stock 2010-15 Camaro SS automatic tune had a 6300 rpm extreme fuel cutoff, which supports your statement, but this tune wont be quite that aggressive. My buddy just wanted...

    I appreciate the quick response, I'll haven't done much with the actual shifts yet because it's a vehicle my buddy shares with his wife. The shift table alone has been a massive improvement over...
  5. Tuning 2012 Yukon 6.2, Need Redline Advice

    Wow, the stock tune on these things is super conservative. The 1st gear WOT shift is 5725 rpm, 2nd and 3rd gears are both 5425. Is there any reason I can't go 5900 for all 3 gears? Stock engine...
  6. Tips for tuning a '12 Yukon Denali 6.2L/6A?

    My buddy got a Yukon Denali recently and he's trying to improve it on a modest budget. We installed an LS3/LS7 90mm throttle body and a really nice Airaid intake. Now I'm writing a tune for him. I...

    When you say "added 5% to the MAF (for an aftermarket intake)" what table are you talking about and what is the improvement?

    Thank you! I'll tweak things and see what kind of KR I get. Course, it's fall now and I probably wont see intake temps over 80?F for 6 months.

    I'll be making some changes to my intake soon that...

    If you have the factory tires on the car, check the speed rating. You really don't want to go 250 kph on tires rated for 180kph.

    My IAT table seems like it starts pulling timing really aggressively. I don't have a wideband to tune it perfectly, but I was wondering how much breathing room I have to improve it just based on the...

    Power Enrichment just bumps up fuel delivery when you're calling for power. There's no downside to making PE more aggressive except that you're using more gas sooner in the throttle. I have my PE set...

    Hey, I turned the crank refs way down, 15 for both the entry blend and the dfco delay with pretty minimal improvement. Still feels like there's something in the way of my changes.

    I'll be honest,...

    What's holding up DFCO in my tune?

    53009

    I've changed the enable/disable rpm to 1300/1000 for better access (it was 1600/1200 stock). Enable speeds are fine. I've dropped the blend time from 150 across the board to 50, raised the...

    Glad to help.

    I would recommend setting your PE based on one parameter and dialing the other limits back somewhat so you have clear control. IMO using those two parameters together will just muddy...

    I think I can actually help you with this one. The point of PE is switching the air-fuel ratio to make more power at the cost of efficiency. It's very conservative from factory, but if I recall...
