Just bought the SCT 3015. Any thoughts or opinions? Anything I need to know that I haven't read about? Any websites I can download tunes from?

 

Hard question assuming that we know nothing about what you have already read or learned, wouldn't ya say? Plug it in, and run one of the canned tunes. After that, do a little soul searching and figure out if the canned tunes are good enough, or if you want a true custom tune, and what your acceptable wait times are for a custom tune.

What other mods have you done, and what are your expectations from the tuner. There are some talented minds here who will gladly help you, but the more info you can provide up front the better your answers will be.

 

It's not THAT easy. Tunes are not free, other than the canned tunes that the device came with.

 

Okay I'm trying to find out what my tire revs per miles are 35x12.50x17r. I just recently took out my cats and turned off the rear o2 sensors. I have Cold air intake, and mass are flow sensor. I have a borla sido exhaust system but when I get the money I am going to change it to true dual exhaust with magna flow glass pack.

 

To figure it out, you need to know what the tires are exactly, as lug depth plays a roll too. Also, you might consider what air pressure you run to accommodate "squish" correctly.

As a general rule, 600 rpm

 

No need to calculate real close - you fine tune it by comparing the speed readout to a GPS.

 

Yeah my speedometer was 5miles slow now its 5 miles fast haha I just need to readjust some the rev selection.

 

Tweak the tuner speed readout to the GPS, not the speedometer. The speedometer by design is a couple MPH fast.

 

I've got it at 2mph fast which is fine with me.

 

Okay so I uploaded the custom performance tune and my gas mileage has increased to 20.4mpg torque and hp has also gone up. This thing is amazing.

 

So we never heard who did your custom tunes did we?
