Quick question running looney tune

[sootman73]

I just got the tune loaded yesterday and like it, its fast and fun.

Today i did a 4wd launch from 0-95.

I coasted half a mile and then turned around. backing out the driveway and going back to the stop sign again there were sparks coming out the tail pipe!

I dunno what my EGT's were as i haven't gotten my gauge yet. Doesn't seem to be anything wrong with it and it doesn't sound any different.

could this just be soot burning out? its been stock for 155k miles and it checks out in every aspect, in great condition. Did i just hold into it too long?

I suspect you just burned some of the soot out like you said.

I wouldn't hold it that long until you get an EGT gauge installed. I know mine always would hit 1600-1800 degrees before I got to 95mph with the looney wild. Basically I was forced to let off before burying the speedo.

I'm not going to anymore until I get one. 1600-1800 degrees? i didn't know these trucks could handle temps like that?

I suspect the soot burning out idea also, especially since it was described as sparks BUT I have had a gasoline (yuck) powered, turbocharged engine have a cat failure that sent glowing rocks out of the tailpipe.

Well if its just the cat burning out then I'm not worried. lol

And 1900? jeez, I don't think I touched 1900 but i guess you never know....
