Hey sorry to say it, but I didn't get the big warning slip in the package. Nor did I come accross that anywhere on their site. I do get the warning not to tow for the mileage XS tune, but the only warning I get for the performance tune is to use 91 or higher octane. As far as the user guide that came with my Cortex goes, under "Performance - Cars, Trucks, and SUV's", it states "Tuner will display Tow Limits, if applicable. Do not exceed." And believe it or not, the tuner does not display any tow limits when I set the tune. So yeah, maybe they could be a little more clear. Or do they expect you to search every obscure internet forum on their product. i.e. http://www.flashpaq.com/forum/viewto...ghlight=towing?
Again thanks for the info...I do appreciate it.

Can anybody who has regeared tell me what kind of issues to expect...like speedo and odometer error...trouble downshifting/upshifting...Will I need a special tune to correct these things? I've read that some people still have issues even with a tuner...Also, for those of you running 4:56 gears, what's your RPM's like @ 70 mph. I have the 5 spd tranny so I realize mine might be higher or lower, but I don't want to be screaming down the highway @ 70 mph.....BTW, thanks for the above-mentioned warnings about towing with the performance tune. I probably should have taken a closer look at the manual but I never gave it a thought...
not the first time I overlooked something important though... Thanx again.

Most people with issues with gear changes who have a tuner, have a vehicle that reads off the tranny for the speedometer/odemeter. Our trucks read off the ring gear, so you'll have no problem setting it with your Superchips.
There is a lot of poor speculation going around that 4.56s will have you revving crazy high on the interstates. The truth is, I'm up around 400 rpm at 70mph from when I had stock tires on my stock 3.92 gears. Maybe enough to be down 1/2 MPG while cruising 75+ mph, topps!
That little bit of extra rpms will mean a LOT less upshifting and downshifting while towing because it will get you into the Hemi's rpm "sweet spot" faster and keep you in that zone longer.
If you can afford to do it, re-gear, you won't regret it!!!
