Since it seems like maybe this got fixed is this going to be a new program that will be uploaded such that if I update my tuner I will be able to get the same program? Or it's just a custom tune for that individual? By the way thank you very much for your time and effort.

Anyone there at diablo?
I hope this thread does not go dead, I also have this problem and it's exactly as described and have a drop in K&N replacement air filter just like the original poster. The symptoms are the same you get a banging when you're at wide open throttle with your foot mashed all ...

What problems are you having?
The 1 to 2 shift is rough, at wide open throttle it bangs hard 1 to 2 and 2 to 3. When you're not at wide open throttle it bogs down between 1 to 2 shift like it shifts too soon into 2nd. This has been reported and talked about over and over again with many threads ...

this is exactly why we advise that you restore before going ot the dealer.

Please fax or email proof of the dealer reflash then call with the tool powered up and we can reset it, it also needs to be updated on a PC.

Thanks
I case this ever happens to me...what is the proof of the reflash your ...

Spent all day on the phone with customer service. Finally restored the tool with a new pass code. If you have a similar issue just call customer service.

Do you know what the problem was? Why did the update cause that to happen? That's why I'm afraid to update mine. I wish they would post when ...

Any new updates that might address the above issues yet?

Any updates on this issue?

If you're still investigating why not take a look at the log files that we have posted multiple times. Wouldn't that help your investigation?

I'm getting the impression that no one here is willing to take a look at this. I'm coming from a background of owning a 99 Silverado that for years I always heard about tuners and how great they are. I always wanted to get a hypertext programmer back then and wondered how much of an improvement in ...

you try adjusting the shift points higher? don't know if just adjusting them by rpm will help with that.. may need to have the mph setting changed via custom tuning..

There doesn't appear to be a place where you can adjust rpm in partial throttle. In the adjustable settings when you open it up to ...

Seems like me and you are having the exact same issue...is your truck 4x4? I've noticed more guys having these issues with the 4x4 trucks. Not sure exactly why that is but maybe something with the transfer case could be throwing off the tune? But i doubt it. But then again anything is possible ...

Yea the bang at WOT a lot of people saying its axle wrap but there's WAY too many of these brand new trucks doing it to be axle wrap. I could see 1 or 2 having something driveline off balance or out of line... But it seems like every truck running a diablosport tune is getting it.... Leans way ...

Thought this was fixed in the last update. Have you tested the WOT shifting yet from a stop? My truck still has a slight bog down at low rpm shifts but bangs into gear if I have it to the floor. Think Diablo needs to get another 2014 on the dyno n do some real world testing to get these issues ...

Bump.. u guys must be busy or something, haven't heard back in 8 days since posted on Sierra thread.

I posted this within the Sierra thread but I'm not sure if anyone checks it anymore.

have a 2014 Silverado and I'm experiencing the same things as what is written about. I don't know if the 91 octane tune has the same problem but I'm running the 87 and when you enable throttle boost, it definitely ...
