Sparks and Coils - Performance Decrease
Hey guys, I'm running into a bit of an issue with my car as of recently. Just a few days ago I had changed my Spark Plugs and Coils, and since the change I have noticed a decrease in power, not sure if I may have installed something incorrect or what it could've been, spark plugs were gapped to 0.022.
I'm also running a stage 2 MHD tune with front mount intakes if that would make any difference, no aftermarket mods aside from that. In addition to that I noticed when I let off the gas when I'm in Sport+ usually the exhaust goes BRRAPP, no more of that which is sad. Cherry on top is that my intakes sound a bit quieter and when i let off the gas it sounds like I have BOV valve?? Any Help would mean a lot, TIA! 2016 M3 56k Miles https://www.fcpeuro.com/products/bmw...12138616153kt6 https://www.fcpeuro.com/products/bmw...silzkbr8d8skt1 |

Sounds like you may have cracked the stock plastic charge pipes and/or the o-rings have perished, causing a boost leak. Do you have bootmod3 to log the wastegate duty cycle and boost?
