Thx For The Honesty Jo8m3 I Always Thought Of It Being A Sound Or Audible Mod, I Guess Thats Why Some Do The Ecu Tune To Get Some Oomph Behind The Sound.
I Owned An Audi A3 2.0t Which Got 50 Hp From The Ecu Remapping
Wish That Was The Case With Our M3, Also Only Paid $300
Vs $900 For Only 15hp For The M3
