I purchased a Superchips Flashpaq 1865 for my 2011 Ranger 4.0L. Installed the performance tune and changed tire size to 33" tires to calibrate my speedometer. I definitaly dont notice a difference in power and it didnt calibrate my speedometer properly. My speedo was out about 10% before and is now out 5%. I have stock gears so i didnt mess with that part of the tuner..

Anyone have this issue??

What tunes/adjustments did you guys do with your flashpaqs?

 

I know with my Predator it took a while to get my speed dialed in to match my GPS. Does the Flashpaq only give you specific tire sizes or does it go by revolutions per mile like the Predator?

 

Only lets you select specific tires sizes..

 

You gotta play around with it. They arent made to give more then a couple hp

 

I dunno about superchips. SCT let's you select tire diameter and also axel gearing.

 

I have the Flashpaq and put every spec you can and I'm right on my gps. I run economy tune but still has enough power.
