Intune - 6spd - 3.92 Gears

[Mark182005]

Hey guys, I'm really confused right now and would like some input from you experts. So before I installed the Intune, at 100km/h (roughly 60mph) my RPM gauge was pretty close to 2000rpm, 1800-1850rpm to be precise. At 120km/h (roughly 75mph) I was just over 2000rpm, 2050-2100rpm to be more precise.

Now I have installed the intune along with new calibration settings and at 100km/h i'm at 1650-1700rpm and at 120km/h i'm right on 2000rpm.

I haven't changed any gears, tranny parts etc so I shouldn't see any changes in RPM at certain speed.

Anyone have an explanation to that one?

The only two options I can see is that the display on my Tachometer is off because of the intune or the intune's update in the PCM calibration settings updated my old messed up settings...

Sounds like the tire setting is just a little off on the tuner. I would just adjust the size in the tuner and compare your speed to a GPS to make sure its accurate.

Makes total sense!!! Thanks for the help!!

That's exactly what it was. It was set at 32" and I am running stockers which are 33"!

Knew I would find the right answer here

Took advantage and added a little 5% to the throttle booster
