Florida-based tuner PSI reveals their M3 Coupe project. The super sporty blacked out M3 gets under the hood the G-Power SKII CS kit which on Dyno scored 502.6 wheel horsepower with the supercharger in SAE correction, significantly higher than the 339.3 wheel baseline. Engine Modification include 8 fuel injectors with enlarged mass flow and 8 colder racing spark plugs for an optimal ignition timing.
The M3 Coupe also gets Eibach Race Springs along with G-Power designed 20″ wheels. To further enhance the exhaust note, an Akrapovic Evolution Exhaust System was fitted to the M3.
Inside, the M3 Coupe was revised as well to include VEI Gauges (AFR, Boost, Water Temp), along with the gauge pod made by 3D Design.
