By other hand, under power on the car behaviour is ok, no problems.
Thanks in advanced!.

P.D: Sorry for my english, but is not my native languaje

With a 3.5r bolted to the car the best modification to make is to simply add wings. Your car should be airborne by the middle of the straightaway.
I would drop down to a 10.5 which for 12th is very fast.
