My wife's tahoe is the most gutless V-8 I have ever had other than my high school hooptie 77 cutlass. This thing just falls on its face after 1st gear and any push of the gas below 4k rpm's in any other gear its just pitiful.

What can be done, I know you guys have to have seen this before.

How can I get some more ass out of this thing short of throwing an LQ9 in there?
