if you had two cars you would need 2 jb4 piggy backs, so no difference ...only that there may be resale value of the jb4
but i am sure we can also install back the original software when we sell off the car and ask the new owner for a nominal fee to have the ess map
roman ESS ... is the 35i map stage 2,similar to the 35is stock map ???are the boost the same ?
after tunning to stage 2 will the 35i be on par to the stock 35is ?
cant decide but leaning towards ESS as dont want the jerky feeling with jb4
TIA

ESS on our 2012 35is. Totally stock other than that. About $1,000.
JB4 Stage2, Map 1 on our 2012 335 xi (E92, AT), AE performance exhaust and BMS intake (no power addition). No DPs, so can't run Map 2. About $500 for the JB4 and $1,800 for the exhaust.
The Z4 will walk away from the 335xi. EXCEPT, if it's pouring rain and we are taking off from a stop (just the AWD vs RWD). The Z4 sounds so much better too.
But, I have needed to remove the ESS tune a time or too, and each time I had to email ESS for the new software version. Apparently, they change it out or it's set to expire fairly often. But, each time I asked, they were very prompt to email me the new software and answer my questions. I just wish I never had to ask for the new version. At least with JB4, I can walk out to the garage and pull the hardware out in 15 minutes.
