Question regarding this....

I had a jb4 w/bcm installed for a bit and then took it out and was going to reinstall and found it isn’t even recommended now w/bcm and fuel controls just curious why?

Was this found to be causing problems?

I used the fuel and bcm before without problems should I not do it this way, bummer this got canned I enjoyed the idea of e30 again

I understand the risks just curious

Will I still get all the functionality of the jb4 w/ logging and code clearing etc for my high flow *** less pipe?
