2011 Ram 5.7/400 stroker

[Javier_Wilde]

My concern is my tranny holding up the torque(545rfe). Can you make the tranny stronger with a tune?.

Maybe adjust the shift pressure with the tuner but idk if you can do it on the new trucks.

How can you make a mechanical part stronger with a computer? You can't. You need to get a SharaDon transmission. Getting a built tranny is the only way to make it stronger.

So is the 545rfe stronge enough to hold up with 400 cu?. Im not talking about hard launching. This is me with stock 5.7... http://www.youtube.com/watch?v=-Z1OgxLrS9g

It probably could, but a Stage 2 or Stage 3 would be far preferable and much safer. http://www.sharadon.com/sdtestparts.htm
