Here is my stock tune for my 2009 Silverado Crew Cab with the 4.8 Liter.
I haven't bought the credits for the tune yet, but was looking for some insight and some help on a good tune for that extra power and bottom end TQ, the truck is a big O pig from a stop and will not even spin the tires even while power breaking lol.. but starts to show the power after 3K RPM's.
Truck is 100% stock from factory. I was also looking for a good configuration file to look at. This is a little different than tuning the HHR SS that I had months ago, there are a lot more things to tune on this vehicle.
Right now I have the Stock Tune file and I will post up a scan in a little while.
Thanks, Geoff.
Just updated this with 2 log files.
