they look different(color,shape), but do exactly the same thing. the flashpaq has a 1 year warranty, the cortex a 2 year warranty. the 2 year warranty is the main difference. but if you buy the transmission management software (it's an upgrade) it voids all the warranty. hope that helps.

 

Just to clarify, the 2-year warranty offered with the Cortex is an additional powertrain warranty on your vehicle. And, yes, if you buy the transmission tuning add-on module it voids that 2-year powertrain warranty. Also, I think the Cortex has some ability to tune multiple vehicles. Otherwise they are identical in function when it comes to the actual tuning.

so will my gas mileage be better or worse?

 

some claim 1-2 mpg better with the tow tune. most don't change or get worse cause they always have their foot in it more often! i think i'll order mine monday..........can't wait!

 

Well I did it! I ordered mine yesterday. But it's gonna be a month before I get it! I got it shipped to my sisters way out in Wyoming. My parents are there and will bring it back to Canada when they come. Crazy I know, but I save about $100-$150. The shipping would of only been $13, but the brokerage fees were $50, plus the duty/taxes. Yes I'm cheap, but I call it "thrifty". So I'm gonna pay $325 Canadian instead of $450+. Cheapest I could find in Canada was about $425 and our dollars are almost even! We get bent over up here!
