so I have 2008 MSP3 and i am about to install a downpipe on to my car. So far i have an sure intake, HKS catback, and turboXS test pipe. but before i install my downpipe i want to have a tuner ready cause i don't want to run lean then zoom zoom boom. so my question is is there anyone out there with a hypertech tuner and a catless downpipe that has any input on the hypertech? Any less will the hypertech tune the air to fuel so my car runs good with the catless exhaust. All i read on there website is that there tuner compensates for the intake only pretty much.
Thanks,
Dan
