Has anyone who has been running a diablew tune for a while now experienced that it loses some of the responsiveness after the truck relearns? It's still better than stock, but not as responsive and fun as it used to be.

I wondered that as well if the TCM would relearn and if it would change over time from the initial Diablo setup. A few days ago I just restored mine to stock then reinstalled it and only modified AFM from off to back on and throttle from 0 to +2, then same firm shift with no changes. I swear shifts seems better. These model trucks are just an oddball of well odd happenings lol.

 

I was just reading the thread on turning off grade braking that apparently helps shifting. Odd, just odd.

I have received numerous PMs asking about my tune, so many in different threads, I don't believe I could find them all, so I thought I would just initiate a seperate thread to address it. This may be

I just had Black Bear tune done and wow my truck at full throttle shifts into 4th at 100 mph. Transmission shifts so much better. Throttle response is fantastic. Best tune I have ever had done.

Ok, there seems to be a little confusion and a lot of misinformation passed around the internet that WILL eventually bite one of us in the butt when they go in for a warranty after they get their truc

Are you running just the regular diablo tune or diablew? I wonder if the grade braking would help lol

Just the canned Diablo 91/flex tune. Which I've been pretty happy with. I have not experience much odd shifting with it. Only a rare clunk during WOT shifts. Are you using a Lew tune? How is it over the canned one?

I liked it a lot better than the 87 canned tune! It still is probably, just doesn't seem as responsive as when I first installed the tune. I'm going to try reinstalling it tonight.

i think ive narrowed it down to black bear. I wish they would come to tampa for in person.

 

What made you decide on black bear? Just curious.

Future updates no charge really. Everyone seems to love blackbear and they can get future updates on the fly.

Yep this. I am leaving for an 1800 mile road trip tomorrow so I emailed them a few weeks back for an efficiency tune. I now have a tune for road trips and one for performance daily driving. Since my truck was tuned by Blackbear, I've been loving my truck more than ever.

How long have you been running the Lew tune?

Probably about a couple months now. I just installed a CAI and I'm gonna do my exhaust this week so I'm going to log data and send it to him again.

No problem, it is definitely a lot better than stock. Kinda wish I would have went to a local shop and actually had them do it in person, but I was really busy at the time. I've heard good things about Black Bear too.

The guys were just in Orlando. But if there is enough interest, they will go anywhere.

 

Hi Jenna. Question for ya. Are these new trucks capable of "relearning" after a tune is done so as to modify some of the performance enhancements that the tune was initially intended to change? (Am I making any sense lol )

      TCM Tuning 6L80E

      By Grumpy Bear · Posted

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.
