Ive had my car running great and shifting even better. A lot of fun to drive.
My problem is my MPG is lower than before.
Would it have anything to do with the TCC settings that I adjusted?
I try to keep my foot out id it as much as possible but I can even get 20mpg on a mix of city highway driving.
if these settings are the culprit, how do I keep crisp shifts and get my MPG back?
Im using 100% gas

I can't look at your tune because I'm at work, what were the 'before' settings?
The TCC Settings were stock. I remember reading somewhere that GM set up the TCC settings to me more conservative on fuel consumption.
If you didn't change them, they should have no adverse impact on the mileage. Log your TCC slip and see if it's locking up properly.Quote:

On Last logging the TCC seemed to be working properly
The mod is a mild cam and tune.
I would say those look fairly higher then stock, so yes going into lockup later will definitely increase fuel consumption.
But would that affect Highway driving or just in town?
How about posting a log of some highway driving? Include you TCC pids. Then there would be alot less guessing. :shrug:Quote:

What do you think?
Sport mode wasn't locking at highway speeds.
I fixed that and MPG's are better.
