Is my car running lean?
Hello! I just did a spark plug change to one step colder today and when taking out the OEM plugs I noticed that they are really white and wondering if my car is running lean or is it the heat? I am running Bootmod3 stage 2 aggressive and was running it on OEM plugs for about 15k miles
Here is a link to my datalog https://www.bootmod3.net/log?id=6035...0b432a2b834a6c Please help  thanks -Thevinman01

These cars run lean in normal conditions to save gas, your plugs look fine. Your datalog is ok, but your fuel is not the best for the 93 tune. You have knock at higher RPM and half decent but not great timing.

What intercooler are you running? Am I seeing it correctly that iat skyrocketed around 125* before coming back down to 70?

Evolution Racewerks is the one I have, there's a few options out there. The stock one is absolutely terrible. https://f87.bimmerpost.com/forums/sh....php?t=1458121 |

Ya it looks like he's running stock intercooler, that's likely contributing to the sub par timing.
Right as the iat comes up hard, the timing starts to jump around a bit, OP get an intercooler on that missile please. Lol |
