12-14 degrees is within my idea of a safe street tune when you are making serious power. I'm not ripping on your boy Rob; but, if he sent this guy home to Chicago in the dead of winter with a 16+ degree tune, for 92 octane, that was tuned in Long Island, NY, with the idea that he was good to go, then there may be some relevance to this question.

I too am making 500+ hp on the stock LONG block, for almost a year now. Driven every day and enjoy embarrasing sports cars, too.

 

So what you are saying is that "possibly" it was tuned wrong for the Chicago area? What should it have been at? For a dead of winter.. tune? And was it set to the wrong tune ? Could this have been the problem?

 

I don't know. I only asked the question. It hasn't been answered beyond me being told to shut up. It's a possibility.

 

Forgive my ignorance.. but... a 16 deg tune was set up with the tune that I was sent home with? I take it that is a bad thing..???? Especially for winter conditions? O my aching head

And thanks for bringing this issue of tuning up! It maybe helps makes sense why it would go as fast as it did, with no other signs.

 

A 16 degree tune isn't bad on a built motor; but, if you move the truck half way across the country and change elevation, air quality, temperature, and maybe even fuel quality, you can hit a problem like this. I would have wanted a rich running 12 degree tune for that transition and then found a tuner in the area for a dyno session.

Still, this is only a possibility. Though, I'd say a good one considering that the truck was fine for 3 years and withstood Robs driving style for the time he had it.

 

Gotcha.. im on a stock long block as well.. Sal is a great tuner..

 

Well thanks sooooo much for the Info.... this is the first thing that I have heard here that makes sense about how fast it happened. It was brutally cold here the week that this all happened. Thanks again, I will pass this thought onto my mechanic... Maybe this is it if nothing else is found.

 

I'm sorry, I thought you had Stage II cams for some reason. Good numbers!



Sal is the man. I wish I had easy access to him here in NC. The guy I use for tunes seems to be pretty good, too. I can't complain.

 

I hope you get things worked out. I didn't give any money to the guy mentioned earlier in the thread by Don's Bolt. I didn't trust the way it was brought up to the community and felt that we were being played. In this case, I would be happy to chip in a few bucks, if the community decides to do something. I don't think anyone did anything that was intended to jam you up, and hate how it all has worked out so far. Good luck.

 

i do have stage II cams.. but the heads are all stock... still a stock long block..

 

Thanks allot for the info and your input about the situation. I know that whatever happened was not on purpose or intended in any way, shape or form. It happened, and well time will tell me what it was. Thanks for the offer to chip in a few bucks, that is very much apprexiated, it really is, but at this point I need to see what happened. I will keep everyone posted as soon as I know.

 

Ok lets make this part CLEAR
All three tunes on the xcal were winter tunes, it was dyno'd in the winter, and all three could safely be used with pump gas.

Thee most aggressive tune on the xcal was the 93 Octane tune, that one has 16 degrees of timing and it WAS NOT installed.
(as said I dyno'd on that one in DEC using 92 Octane with no problem)

The Tune Gregg left NY with is the tune I've been driving around with 24/7 since December, the 92 Octane tune. That tune is 13 degrees of timing and it was PLENTY SAFE for 92 but Gregg was told to never use less than 93.

There was also a 3rd winter tune on the xcal which I have never used, 13 was lower than I ever ran before and it ran flawless so there was never a reason. BUT the last thing I did before Gregg left was me pluging in the xcal and showing him all 3 tunes on the display and outright asking him if he wanted me to install the 3rd Winter Tune "his response was NO".
Since I never used it before and had no problems with the 13 there was nothing to argue about, or any reason too... 13 degrees is MORE than safe

 

I agree that a 13* tune should have been safe as long as there was no fuel system failure, or poor gas problem. A tank of poor gas took out my 1st motor. Damn Jersey laws about not pumping your own fuel. When my built motor went in and was being tuned JDM could not get rid of detonation issues. Had to drain the tank to solve them.

If he was still running the 13* tune, and it was rich enough, I would think that he should have been alright. Depending on the changes in temp, air quality, fuel quality, and how hard the truck was driven. It was really cold in Chicago for a while there. I don't think that even a built motor could take those temps much beyond normal driving. I guess a blast to 70 on an onramp might even do it at -20*.

 

How about this, Ill keep it simple.

You buy a used truck with a built motor. s-h-it happens .Oh well , Good luck
