Well my first day at the track with my z6 was a little disapointing. Maybe i had high expectations or sumthin but my best time was 15.7. Although im running and automatic ecu, have an exhaust leak and couldnt luanch for shit i though id atleast pull a 15.2. My mods are headers,b18a throttlebody,test pipe,catback,si trans, short shifter. I also have the wrong throttle cable that wont let me go full throttle. this is in a slightly lightend ef. Anyone have an idea what i should be running with this motor?
