Im looking at going to a BW S362 for my 06 (sig below), truck is used both DD & some sled pulling. Need some input on choosing the AR, going with a T4 for sure and they come in either .91,1.0,1.1 AR. I know that the smaller the AR the quicker spool, but the higher AR is better for top end HP & better turbine efficiency. Im not a turbo guru by any means so any extra input in this area would be appreciated thnx!
