2 quick ????'s

Now that i have the TS6, when i get on it, the check eng lite comes on. I think i remember reading on here that it is from high boost press. The lite resets itself after a few minutes. Is this whats happening.

Also when driving slower with the chip set to 100 or extreme, the shifting is pretty hard. I'm guessing the shift points are set for running hard on those settings. Is there anything that can be done for that, or will it eventually take out my tranny?

Both are normal conditions with the extremem settings, the check engin light can be fixed with a map sensor fooling device from black cloud or Dfuser.....as far as the shifting, it could be detrimental to the trans over the long haul if you drive it too often that way just to have it there, but turning it up and just running it hard from time to time shouldnt hurt a thing...

When I had my tranny rebuilt they told me when it starts sliding into gear thats when its going out. I don't know if its because of the billet converter, but it shifts pretty firm.

My old TS chip did the same thing. In the 140 it shifted pretty firm all the time, on it or not. In the 100 it seem to shift hard only when I was on it but would calm down and shift smoother under lighter loads.

If its shifting firm then its not slipping. Thats a good thing.

As for the check engine light, normal for those types of chips.
