Do you have the instructions that came with the kit? I would be interested in taking a look at them to see how big a job this is and what needs to be taken off the car etc. during install before I could decide anything.
Can anyone tell me how in a 2011 auto GT each gear top speed would be affected if my tune shifts at 7K opposed to 6800?
Is there a formula or way to figure out the difference or is it a test and see type of thing?
I got this from another site so take it for what its worth:
Top speed in 1st...
Wish I would have found this post on my phone last weekend when I was under my car re-torquing everything!
Thanks for all the information this is great!
