I'd hate for him to go bigger on the stall if he doesnt need to. FWIW...i started with a 3200...went to 3400....3800.....and now am back with a 2800 with the same 60' but of course much better driveability. I have tried the N/A way of thinking..more gear and converter and never picked up...only lost off boost driveability. I'd still like to see what his truck does with a 2 step.....of course the bigger turbo may need more stall to get to the rpms where it starts boost. Remember his 2800 stall is gonna stall higher with the torque of a 408.

OH..nice numbers BTW..forgot to mention that Cant wait to see where she ends up!!!!
