JB4/MHD BACKEND FLASH

[nuffsed76]

Hello fellow members I just recently got my DME Femto unlocked. Just wondering if I should keep my JB4 connected and do a backend flash or just run with MHD and no piggyback unit. Yes I know this has been brought up a while ago just wanted an update to date opinion from the forum thanks

Literally zero reason to and your engine and transmission will thank you.

Ok thanks for the reply saw some people say it would make more power and maybe it will but not at the cost of my engine and transmission

I am running a backend flash because the MHD OTS stage 2 didn't perform nearly as well. @ColonelAdama got me dialed in! Little 60-130.

The JB4 alone outperformed the MHD stage 2 flash??

JB4 + MHD backend flash did, yes.

Just for anyone considering selling their JB4 after unlock ?

Basically the ecu flash gives the JB4 the proper fueling it needed all along, and let's it continue to manage boost control.

My JB4 is sitting in the box in my garage since I went MHD. My car ran fine on the JB4, but had some issues in really my cold temps. I wonder how the JB4/MHD combo performs vs a custom MHD tune?
Either way, awesome people are making power in different routes!

Doesn't hurt to try. Can always flash back OTS if not better. PM me if interested.

Won't be able to push 7s without meth though.

Appreciate it and maybe something in the future...for now I am having a blast with the OTS stage 2 tune and catted AA DP. We also don't have e85 around here, wish we did!

Probably less gains to be had on 93 only, so enjoy what ya got!
