Off the shelf Cobb tune

[SCAR911]

Has everyone been happy? Any issues? I've always had dyno tunes done or a lot of logging with a laptop on the street. Also, I'm assuming this ends the factory warranty?

Also, does a off the shelf tune give much of a difference?

I run COBB OTS tunes last several years. They are very safe and pick up the performance quite a bit. Best 1/4 with OTS stage 2 COBB and good air is a 13.1 et . Next year pulling trigger on manifolds and bigger turbos. injectors , Goose tuned all the way then .

Ran the Cobb OTS for about 6 months and was very happy with it. That is until I downloaded an update Cobb had for their A.P. Was very unhappy with the way my truck ran after. Called Cobb to see if I could go back to the original tune and was told no, it's a done deal. Decided to have Goosetuned do a custom tune to my truck. Very satisfied. Should have just done that in the first place.
