. I would ask the same thing before I dropped a chunk of cash on the unknown. Thats a good thing about these forums ,You can use peoples experience and not waste your money on something that doesn't work well. Nothings wrong with your thread,no reason to be sorry.

 

The guys with the cortex, was it a big change in power and such?

 

A lot more gettie-up and go. When you set the thing you set t to pro and you can turn off your electronic speed control, rev limits, shift points and pressure. When I maxed the damn thing out and put my foot in it the truck took off! I cherped the tirers going into 2nd and 3rd. It is a difference unlike u will ever see from just throwing in a new intake or anything else really. ONLY ISSUE IS. AS OF RIGHT NOW!! The cortexs only supports CAI kits. BUT!! That's gonna change real quick to support coil pack kits, exhaust all the good stuff.
