I have an sct x3 with custom tunes from VMP. I am currently running 87 performance on my truck right now. I just put on a Banks monster exhaust. It is a single side exit just like stock. Do I need to change this in my tuner since it is not duals? I am thinking I should because it definately flows better than stock exhaust. How do I change this? I am also going to be getting some bigger tires in the future. How do I change the tire size in the tuner also? Thanks in advance.

 

have you talked to Justin??

 

I sent an email but no response yet.

 

anybody?

 

Call Justin...

 

As far as tuning goes- Wait to get ahold of Justin. Tire size is easy, you need to figure out how many revs per minute your tires rev. Then you go to program vehicle-custom tune-adjust options- then there is a menu to adjust revs per mile- thats where you select it. I just used my GPS to figure out mine since the tire calculator's numbers were wrong online... I just kept changing it till it was spot on..

 

I'm pretty sure you meant REVS PER MILE. Right?

 

Yes I did! haha thanks for the correction, it was late..

 

But, at 60 mph, it becomes revs per minute doesn't it? Think about it. LOL

 

Yes but it would also depend on the GR, your time zone, and DST.

Right?
