Switching from JB+ to JB3..

Well I just got my JB+ a few days ago and I set it to max and did the solenoid bypass right away and I really felt the power difference. It will break the tires loose all the way through 1st gear, and jump out sideways spinning the tires into 2nd gear..but I still have stock 225's so that is somewhat expected. Fourth gear pulls very hard all the way up until 130mph when the STUPID damn no good limiter kicks in!!!! But it's just a tease when the JB3 is out there and there is more power to gain. My main reason for buying the JB+ was because it is very easy to install/un-install before going to the dealer for service. But the JB3 PnP doesnt look like it would take much longer and for the amount of power I will gain I think 20 min of my time is worth it.. So JB3 it is!

It can take more than 20 min, just be warned.

There is something to be said for the ease of install/uninstall on SSTT and JB+

i had the JB+ and its a negligible gain, if any at all, at past 75% on 91 octane. At the higher settings you would need higher octane to feel the benefit.

Last time, 11 minutes to remove JB3 and 12 minutes to put after dealer visit.

Very easy install/uninstall
