Technically you're suppose to.

 

Ok first your new use search this question has been asked 10k time. All mods require tune

 

Regardless of new or not, a simple Yes would have been ok. I know it's anoying. But it doesn't hurt to just type "YES" than...

No hate, just an observation.

 

Bud get ready for those pop pop's without a tune. Essentially, almost all turbo vehicles do require a degree of tuning accompanying power mods.

You can drive it without a tune, however, a tune ensures proper calibration and you get optimum benefit of your added mod.

Great advise

I had to cancel the order things are tough money wise for me right now. Sorry I didn't look to see if anyone put up other threads regarding this situation I apologize. Thanks for all your help.

:angrydomo: Don't be sorry. Lots of people just ask before searching. Save monies before dipping into mods, you'll need the cash.

Yes mods do get expensive and once buy them from a reputable R/D seller like ETS you will get nothing As crazy as it may sound. I saved up for mods prior

oopz pardon for my incomplete post above...........

ETS mods will get you lots of compliments thats been my personal experience with the company. You have a best mod going for your car just try and save as much as you can and get it properly tuned to match the brand and the mod.

I did save up just my mom lost her job so it's time to save up since I might have to start chipping in with the bills. Worse comes to worse if things get bad I'll sell my ETS V2 Extreme exhaust system.
I figure I just ask since everyone seems to know what there talking about on this site.

 

I know this thread is two months old, and have read lots of posts ..and this question is answrred alot, but i feel no one explains why. As im also confused. If the first 02 sensor is your main reading and the 02 in the cat is just for emmisions, why would a high flow cat affect your tune? I understand that it would flow better, but how would this cause your motor to run lean? I dont post much on hete but read in this site everyday, can a guru explain? Thanks in advance.

 

The O2 sensor only affects fueling under closed loop (idle/cruise), not wide open throttle (open loop).

 

So since your turbo will spool faster than normal your afr will be the same but will not be in timing with the spool? Im a little confused because i dont understand how the afr would change.. Just the spooling of the turbo.

 

If the turbo makes more boost because it doesn't have to work as hard then there is more air going into your engine, more boost means more AIR the 'a' in afr.
