slickmetal · 04-04-2011, 02:59 PM

Intro: Went to the track this past Sat night and a guy was there with his stock Cobalt SS, and was running low low 13s and finally a 12.9...after inspection it was stock but was running just a custom tune. He told me and guaranteed/tested it was undetectable by GM/dealers.

I want to go with a tune by him but he asked me several question but I need help with the following:

1. Shift firmness
2. Redline changes

I have a 2011 L99 A6. I know there is a slight difference is "S" mode (M without tapshifting) and "D". From what I read "S" mode was a little better...Any recommendations/cookie cutter adjustments for one or both modes? I would have went with Jannetty tune but it would be recognizable and void my warranty...

Additions to the tune are LT headers/hi flow cats and CAI. The ported TB will come in later.

Thanks for your assistance!
