you can run it but i recommend getting a catless downpipe asap.

Why do you suggest that? im scared about BMW servicing when I get an oil change or for maintenance. Will a DP be an issue? Also If I do a DP a CP is a must right?

Is meth safe for long term for the engine?

I need to run a log, but how is everyone else's boost psi on map 5? I can tell reduced performance since my map 5 and wire upgrade. First week was awesome, now I'm only showing 12-14 psi max where before it was 16-17. So, until I can get logs to Terry, I've been running map 7 on e85/93

I have bms dp and bms intake. I have sent Terry map 7 logs beta and they look good. I'd say true race gas feels stronger, yet negligible.

So, seems safe to me! I run 50/50 e85 and 93, however. 99 Octane?

Don't switch between maps if you're in map 5. Just keep it there because switching in between them can cause map 5 to reset to 14 psi, I think that could be the problem, I don't know the exact order on how to reset map 5 so I just don't switch to any map including map 0.

is it worth the trouble of updating the jb4 if your never gonna run e85 and dont have a dp/cp?

[F335i]

not worth the trouble in my opinion. The newest updates are pretty much for the map 5 auto-learning when you put E85 or other gas.

But the auto learn adjusts boost depending on the cars performance.
How can switching maps
Limit boost levels?

I know this is an old thread but just e-mail terry and see if the new update still causes map 5 to reset when you map switch. Post back and let us know.
