BMW 1M GIAC chip
Hello To my Fellow M-fans, owned a 2009 M3 and now 2011 1M. I gotta tell you what a difference in the cars. I really am a big fan of the 1M. I upgraded with GIAC chip and what a difference. The car is magnificant.
1. GIAC stage 2.
2. all cats gone,
I can tell you that it would walk away from my M3-dinan exhaust-mid. CAI, Pulley and CHip.
much much better gas mileage.
I live in S. Florida and its black. Mustang Dyno 358 to the rear wheels.
1/4 mile 12.3 at 114 mph, and alot of spinning in 1st gear.
GIAC is really great at what they do.
To all my 1m fans GIAC, CAI, exhaust . the car becomes a monster.
