    2018 Silverado Midnight Edition 6.2L
  1. What tune are you running? Did you pull any tq management out? Any notice power difference?
  2. From what ive been told the 17/18s once its tuned your warranty is done. Something about onstar diagnositics or w/e. I've been running the range on my 18 for a bit. Just hit 3k miles and ordering long tubes soon and scheduling a dyno tune appointment. Only reason ill need warranty is for the bs afm crap.. If it takes a shit then good reason to throw a cam in it. I look at it this way, why pay $49k for a truck and be worried about it, enjoy it and if shit happens and a lifter hits the bed then fix it.
  3. Yeah i mentioned all of that to them and they said this new version has NO battery draw. My leds do not illuminate till i start the truck.
  4. Yes but the speed engineering x pipe duals is not same length. Doesn’t that defeat the purpose of the x pipe? It still follows the same route as the y pipe meaning drivers side pipes are longer than passenger when it hits the x pipe. My 6.2 is all 3.5” from the factory. So the long tubes would be my biggest gain.
  5. Ok so im looking at speed engineerings x pipe kit. Does this really make more power than a y pipe? The x pipe still has a longer drivers side pipe before reaching the x pipe. So passenger side pipe is shorter and drivers side is longer. How does this give equal scavenging and make more power than just a y pipe into 3.5' cat back?
  6. Dam i guess i gotta fork out some more money lol. I already have CAI and catch can. Need to order some headers now and find a x pipe setup. Then get it all dyno tuned on e85.
  7. Hmm ill watch that now and do some more digging. I've seen guys with 6.2s gain 80hp with just long tubes, y pipe, e85 and cai. I was going to go that route but if i can gain more doing x pipe might as well. The dynos ive seen with those mods are right around 420/450 to the wheels. Id love to be around 450 without doing a cam or boost.
  8. How much more? Is it worth just buying the headers and having a shop fab up a x pipe setup? Is there any companies that make a bolt on x pipe kit from long tubes back?
  9. Ive been using a range afm on my 2018 6.2 now with no issues. I called range directly and they had came out with a new firmware not to long ago that works great with 17 and 18s. They also told me the new firmware has no battery draw.
  10. How does the 6112 compare to say a fox or icon coilover?
  11. Definitely looks like it ran harder in the first video. I’ve only launched mine in 4 hi and left it there. Is 4 auto safe to launch in? Here’s a video of my stock 6.2 4wd launch.
  12. 3.42 is the highest ratio you can get from gm with 6.2 and 8 speed. It only comes with max trailering package.
  13. A local shop told me they could install the sensor and tune it for e85. No 6.2 comes from gm flex fuel ready. I was just at that shop the other day, he said they’ve tuned multiple 6.2s on e85. All the e85 tables and everything are there on the factory map, just need the sensor.
