Will an offroad x pipe make my car a lot louder?
The ECU is the computer in your car that's what a tuner does is reprogram the cars computer also known as the ECU. The tuner comes with 3 custom tunes a street tune a performance tune and a race tune, at anytime you can take the tunes off and return to stock. So if you have emissions put the H pipe back on plug in your tuner and return to stock, then once it's over put your X back on plug up your tuner put whatever tune you want back in and your ready to go!When you mean ecu is that just the factory tune? And with a tuner does it always have the factory tune and the 3 tunes? And that's what I'll do is switch the pipes
Nope, they will still remain on the tuner and once you put the X pipe back on just go back and you will see the 3 tunes still there and pick either the 87/street 87/performance or 91/ race tune to put back into the cars ECU. And your good to go!And it won't erase the tunes you had with your x pipe?
