Hey guys, Im buying my 335i mid summer and im new to the e92 club and i dont know much about forced induction cars let alone twin turbo cars. I plan on getting the JB4 right after I finish my visual mods such as front lip, grill, angel eye led upgrade ect. BMS has the JB4 with the intakes but then then im sucking in hot air. Is this okay because theres an intercooler? I have no idea. Should i just do the tune then get a CAI with a shield after or should i get a CAI before?

Thanks guys


EDIT: Also meth injection is something i plan on doing, as well as a BOV. I know i need a charge pipe with a meht bung, but do i need to get a special charge pipe for the BOV as well?
Like i said i dont know much about FI

Check out burgertuning.com, they explain while you ARE sucking in hot air you are still sucking in a TON more air. SO the end result is still more power, and lots of it.

I avoid BMS as they aren't the most ethical company.

I have an N54 335i with BMS DCI and just installed the JB4 last Friday and I can't believe I didn't do it sooner! Very easy install and you just need to reference http://www.n54tech.com/forums/showthread.php?t=10605 for all of your answers. Map 5 with some E85 mix and I was sold. I haven't heard any specific examples about them not being ethical. All I have ever seen is very positive reviews with Terry and I have been researching the JB4 for months.

Awesome thanks! Whats the difference in maps and do i need to change the map depending on what gas il be using? I will be driving from ct for fl a few times and both florida and ct have 93 octane but some of the in between states don't.
