Heres the deal. At WOT my truck shifts hard into third. Not firm, it feels like it is slamming into third and I can hear an audible thump. I have had two revisions for this issue and although it seems a little better it is still there. The weird thing is it only does it fifty percent of the time (When warmed up). I thought maybe my PCM needed to learn the tune but it has been a couple hundred miles. My question is this; Eric is a busy guy and before I bother him for another revision can I fix this myself through the adjustable parameters of my intune? Right now it says my shift firmness is stock, which i find odd because it definately does not shift like it did when stock. Thanks for any advice.
On a side note the best 0-60 time I can get is 7.1 seconds. I know I know its a truck. But this is one way I can compare tunes. Does this seem slow for a 91 tuned truck?

My Let shifting was extremly hard shifting into gears, after 10 revisions it never got any better. You may have to tell him to put it completly back to stock settings for it to not bang so hard.

If you know your 0-60 what track are you @? What's your 1/4

Stock they are under 7 seconds, the tires shouldn't make that huge of a difference. I had Erick dumb down my shifting a little bit as well as I had the same problem. SSI and Unleashed tend to have the smoothest part throttle shifts at least in my truck. It is all in what you like, but on a 91 tune you should be able to do better than 7 seconds IMO.

How are you launching? With all the torque your now making it can be hard to hook up, takes a little practice.

My LET tune used to slam my 2-3 shift really hard anytime above about 50% throttle. I asked him to turn it down and it's a bit more mild, but it doesn't chirp the 1-2 shift as easily anymore :(. Oh well, can't have both I guess.

The one two shift is great. Nice and firm but doesn't have a thump sound like it is banging into gear. 2-3 part throttle is smooth but at wot is very rough. Oddly it doesn't do it every time but most times. 3-4 is smooth as silk.
I am boost launching in 2wd as well as 4hi after I am damn sure the front is engaged. (Made that mistake once)
i have an email with logs into Erick. We will see.
On a side note everyone says the first tune he sends is mild then he turns it up. My first time was the most aggressive but he said he had to back off the timing. Every revision since has felt milder.

How long did you let the tunes learn for? Weird that he has to dial down the timing on a base tune. But every truck is different, and you very well could have had bad fuel.

I was hoping I could remedy this within the parameters of intune but it says the shifting is already at stock
Ya I've been experiencing the exact same thing with mine regarding shifting. I've learned how to use the throttle to get it to shift how I want, but I miss my 1-2 gear chips. I'll have to see if there is anything else he can do to dial it in.

Not sure how the intune works but on my SCT, when you have options still available before you put the tune in the truck, the "stock" option isn't stock, it's what the tuner has it set for.

For example my 5* tunes give me the option to set tire size by wheel revolutions per mile, but when I select the stock setting the speedo is correct, even though I have larger tires. It's selecting the setting setup by the tuner, not the "stock" setting. I'd imagine the intune is doing the same thing.

Also he may be dialling back the shifting each revision but who knows how far he will have to dial it back. Just give him a heads up and keep mentioning it until it is right.

The first two revisions for the shifting I logged within a couple days and sent them to him. This time I let the tune run for a few hundred miles. The Diablo won't let me dial back the shifting at all.
In terms of the timing I had the same problems with the Diablo canned tune. Loud knocking from the engine and black smoke out the back. Erick took care of that but the tune seems much milder. I blamed it on the tune but now I am wondering. I have always ran 91 from the arco by my house. Is that **** gas?

I run Arco almost exclusively never a problem, it's considered a "top-tier" fuel, whatever the heck that means.

Thanks. That notion has really been bugging me. And I was pissed cuz I just filled up. At least now I can rule that out
Did you ever resolve this. My truck still does it on the 2-3 shift at WOT. light throttle to 3/4 the 2-3 is smooth as butter. But at wide open throttle its a slam. Been trying to tune it out, basically back to stock and seems to be still doing it.

I hope oyu figured it out.
