The Cortex (2950) will tune most of GM's performance vehicles, 1994 - Present.
Superchips has OEMFLEX tuning, which means if you own multiple vehicles from the same OEM (GM) and Superchips provides coverage for them; you can use the Cortex tuner one at a time, on all of them.
Superchips allows you to fine tune how much torque will be provided during the shifts based on rpms. Options will include the stock setting, or a 25% adjustable level up to 150%, and then you can go to total TM off with the Max setting. 100% Superchips = 100% removal of torque management at higher RPMS (1/2 -Wide Open Throttle Throttle Position), but at lower rpms the torque management is less with the tune, but still there for a better feel. You can actually go above the 100% Superchips level which would get close to removing all torque management at lower rpms with 150% Superchips. Max it out to completely remove all torque management throughout the entire rpm range.
The second being AFM/DOD Delete. You can turn of the Active Fuel Management to avoid drone if you have an after market exhaust. You may also just not like AFM and would really only want to use it for long trips.
Superchips Cortex programmers are essentially never out of date with regular, free updating of the units exclusively at Superchips.com. Superchips consistently re-engineers their calibrations to stay in-line with the new calibration files OEM manufacturers release and makes them available at no cost to their customers.
Once you choose your options in the Advanced Tune, or if you prefer, the Quick Tune, it takes less than 10 minutes total to tune. The Cortex will upload your stock files (ECM&TCM) and download your custom or quick tune.
Superchips is the only tuner to offer an industry leading 2 year powertrain warranty and a 30 day money back guarantee.
It is totally amazing that Superchips, nor anyone else for that matter has dyno'd their Bone Stock 2009 GT and again after installing their Superchips Cortex Tuner with the Advanced Tune.
Okay, I went out and tested the car today with the new Superchip Cortex Tuner in the Advanced Tune programming. What I really would like to know from others who have installed this Tuner, is at wide open throttle, does your transmission roll up into the next gear when it shifts, verses a nice hard or firm shift?
Mine rolls up all the time, regardless to whether you are at 1/2 throttle, or you are at wide open throttle. Kind of weird if you ask me. Question is, is that normal for this tuner to cause the gears to roll up when changing from one gear to another? All replies would be appreciate?
BTW, I tried it with AFM Enabled & Disabled and no changes in the roll up into the next gear shifting pattern.
