now now girls
But man Engineering is not as simple as people think!
I've been through Engineering twice and emissions testing 7 times and only passed once hahah
Simple guide to passing after all I've dealt with
For emission (free just need to book)
Run stock ECU for the motor you'll installed (no tune)
Run stock cat and exhaust
Run stock 02 sensor
Run E85
I've tried the retune, detune route without luck!
Engineering ($800 to $1200)
Main thing is good brake upgrade
keep the rest of the car stock IMO including real air box and not stupid pod
Most peole do it wrong by moding the hell of their car and power tuning the new motor coze they can't wait
