  1. The pill flip is the transmission thermostat. You can flip the thermostat valve plunger and it opens the trans cooler all the time. This will drop trans temps 20-30 degrees. its an easy and reversable mod.
  2. With the Tri-tune the trans has a "sport mode" when you enable CC. Whether that is a trans tune i don't know for sure? seems a lot like Tow Haul mode. I no longer use that tune it never really seemed to be $500 worth of silky smooth and i would have needed to spend more to Iron it out. the truck ran a lot better after the trans was flushed and an update at the dealer. After that putting the tune back on seemed to undo the goodness a bit. I already had the interface so licensed HPTuners to disable V4 mode and adjust timing for slight knocking issue. One thing i would try is if you have larger tires and wheels is to correct the speedometer. IMO the additional mass and diameter has some effect on the trans torque calculations that may contribute negatively to smooth trans function. only time it really acts odd is cold mornings. On those days i put it in 1st gear and slowly roll out ...get a bit of revs then manually go to second...third etc after a few blocks switch to auto and all is good. Also have the trans "Pill flip" mod ...trans behaves perfectly.
  3. My 128 and 256gb drives are Sandisk cruzer i think. Any one should work as long as it is good quality. If you have the PC for it get USB 3 or 2 they copy much faster. I will reiterate dbpoweramp will rip a cd into any format and bitrate and also add the id3 tags and artwork in one easy shot. the resulting rip is also compared to online checksum database for a perfect copy. If not it will scrub read the disk till it is. If you have a lot of music this is a killer management tool for a collection.
  4. When i turn left pulling into the office each day i do get a clunk on the right side when wheel hits the bump. It is normal as there is some tolerance in the axles.
  5. Same truck from 17 with 55k not ready for brakes yet. Curious the answers you'll get.
  6. Unfortunately highest available here in AZ is 91 Oct. After correcting the High Oct timing map it cruises with almost no KR now so it isn't registering my boom box as KR ?
  7. Its been a while since i scanned it but i had filter set so to capture only multiple knock events. At the same time I could see timing being pulled. I applied a correction based on the scan to the timing and timing stabilized. From an engineering perspective I appreciate the ability for the ECU to control advance/KR to ride on the bleeding edge. I figured the 91 Oct was on low side for an engine tuned for 93 Oct thus more knock on the high octane timing map. I pulled up a scan you can see the timing droop down when throttle went up ~1% and some knocking. I was scanning on a trip and afterward i believe i had injector problems and had to take it in for second time. Haven't had any injector problems since clipping out the KR.
  8. I don't have a BBP tune but was scanning 17 6.2 with HPT and could see i was getting some kr just driving highway as road goes up slight elevations. The highest oct i can find here is 91 so i modded the timing map slightly where it was occurring and the truck seems to run better with 0 kr now. I don't have any hard proof but i don't think constant background knock is good for gdi injectors. Saving a few cents on gas may not be worth it.
  9. IMO the stock springs will ride OK. I just did the 1.75" drop shackles and billsteins and truck is level. It rides a bit rough on rough roads but glides well on decent roads ...better than the stockers. I Added airbags for when when i pull the trailer too keep things level.
  10. get a plug n go kit and an air compressor and keep it in the back. If you get a flat throw a plug in and be on your way in 8 mins. You sound a bit OCD.
  11. I somewhat disagree with the Weight dist hitch crowd. That device is NOT supposed to help SUPPORT the LOAD! its job is to virtually shift the load from the rear bumper to just forward of the rear axle (Like a fifth wheel). If you add too much WDH it is possible the load point can be too far forward. In this condition if you have a hard braking event the front end will dive and the rear wheels will lift/unload and jackknife the rig. Carrying a load is the singular job of springs and air bags. either get beefier springs if you tow a lot or a good set of airbags to keep good ride when not towing. I use airbags and pump them till the truck is level and then set the WDH taught enough that the rear stays planted well not lifting and front doesn't dive under braking. Adding high pressure tires and friction sway bars are also great ideas. I pull a 32' toy hauler right at the max of the max tow pkg in a 1500 6.2 truck with some scary moments till I sorted this out. now it is solid and predictable. Do Not Over tighten the WDH it is dangerous!
  12. I let mine go down to a few pounds and with bilsteins in the back the ride is great. If pumped up to 10+ it rides rough for sure. The bags are not replacing any spring ...they are in addition to springs. add air when you need more spring like towing. I just add enough air to get back to same ride height when towing.
  13. There is a transmission thermostat that bypasses the cooler. It can be disabled/bypassed by flipping over the internals. This will drop temp at least 30 degrees and can be done in 20 mins under the truck. no need to replace anything and dealer uses M1 LV fluid in the trans already afaik. Do a search for the trans tstat mod.
