my WOT logs with stock LPFP logged 4 line items in the 50's (all rest in 60/70's) but never dropped below 52. Was told its normal to drop below requested PSI @ 72.48. So does this mean my LPFP is good (for now?). There is just too many problems i have seen/read with a booster pump solution. If my LPFP is running fine, why should i go with a booster pump? Is it just a matter of time before my LPFP takes a dump? Just trying to fully understand the risks involved with my setup. thanks, Vince Log Attached...

Yeah I thought it didn't sound right when typing it I'll double check my logs I thought for sure it was, This sounds like more for down pipes. Anyway, what do I know..

I have Stage1+FMIC installed. I was reading the NCS DIY guide under BMW Coding sub-forum http://www.e90post.com/forums/showthread.php?t=451145 .
One of the steps is to reset the ECU. I assume I need to uninstall Cobb first? Do the coding step and re-install stage1+FMIC? Or, the ECU reset will wipe out Cobb and cause me further trouble when trying to re-install/loading stage1+FMIC? Thanks for any input. |

This is probably why mine boosts so high, IAT in excess of 100*

18psi is impossible on stage1. if you see could be overboost, or when you let off your throttle. but it's not something you'll target stage1+ agg, I can see it target 18 depending on various conditions (as mentioned a couple of posts above)

^^ Thanks @marv85 for clarifying, I knew I wasn't crazy.
Just checked my logs with S1+ Agg w/ 20% E85 pump blend. I was getting ~18.5 psi - ~12 psi (at redline) when CAT's are under 100°

I need DP's and exhaust next. Or maybe M-Sport rear bumper with CF diff.
I won't touch methanol, out of my comfort zone. I'll just get water misters to spray on the FMIC...

Does the Cobb AP hide CEL codes when you have downpipes?
