    2015 4.0 Prerunner on 285s with stock 373s. At 70mph I’m right at 2k rpm +\- at 75 I’m at 2250 rpm +\-. Trying to figure rpm’s out at same speeds with 410s and 430s. Thanks.

    With 4.10s, the rpm should be around 2,200 and 2,400 at 70 and 75 mph respectively. With 4.30s, the rpm should be around 2,300 and 2,500 at 70 and 75 mph respectively.
