Hey guys,

Currently I have the hypertech tuner on my car and I've been thinking about getting a new catback (most likely Invidia). If I were to get the exhaust, should I remove the hypertech tuning? I'm worried about running too lean...especially after seeing the dyno that someone posted with HT + stillen gen3's. Or will the exhaust not affect the car too much?

 

as far as i know the AFR doesnt change by much with the hypertech, youll be fine

 

The hypertech doesn't change the AFR even close to enough to be a problem. Period.

An exhaust doesn't change the AFR enough to be any kind of an issue.

 

^^ an exhaust for changes the AFR, any breathing mod will

 

Good point, edited to be more technically correct.

 

You will be fine. I have the HT with Stillen Gen 3, ERZ HFCs, and Fast Intentions CBE. No problems.

 

Thanks everyone for the input! Now I won't feel as bad when I get the catback haha

 

No issues enjoy the combination
