V10 RPM's

[SS396CV]

Chris from 5 Star posted an article from Motorhome magazine where they in fact ran a 2014 36 foot Bounder motorhome with the newer engine on a chassis dyno. At 3200 RPM, HP increase 42, TQ increase 75. Remember a chassis dyno will record rear wheel HP which is lower than engine HP (can be 20% loss through drivetrain) I believe Banks is also using a tuner for their results and you can purchase the Banks systems from 5 Star as well.

I installed the 5Star 87 octane tune yesterday. (03 Sunseeker 30 footer) Took it for 40 mile test drive on secondary, rolling hills type roads. I am very pleased with the change in shift patterns and performance. From a start, the RV moves a little quicker. The upshifts are firmer and timed better. Downshifts to climb hills are now smoother and without the annoying 5 to 3 screaming engine behavior. The change to me was not earthshaking but the overall driving experience is now very pleasant.
