M4 G82 owner checking in
Hey all, picked up a 2025 M4 Competition last month. Already thinking about stage 1 tune. Anyone else running a tuned G82 here?

#1 Welcome! The G82 M4 is an absolute weapon. Stage 1 on the S58 is very safe and gives you around 570-580hp. The engine is massively underrated from factory. BM3 and MHD both have great maps for the S58. Just make sure to get a TCU tune as well - the stock torque limits on the ZF 8HP will hold back the extra power.
