Superchips Cortex Programmer Reviews

Did what it said it would but shifts very hard on the superchips value shift pressure, ended up taking it off because i could smell the clutch heating up doing my daily driving.

Fairly good bang for the $$$ 2004 Pontiac GTO

Reviewed By Shane F (Minneapolis, MN) Reviewed for a 2004 Pontiac GTO —8/8/2011 11:36 PM

If you want a cheap way to add more power, the cortex is the way to go. I have an A4 "automatic" and it still breaks loose in 2nd gear. Spinning the tires at 40 mph. The gear changes are faster and more smooth, it adds a lot of torque. Overall a good value. The only downside is that there's not many options on there tune for add ons. The only thing the tune covers is a cold air intake. It doesn't have options for headers w/ high flow cats, or a catback system.

Nice Increase

Reviewed By David C (Ooltewah, TN) Reviewed for a 2005 Pontiac GTO —11/29/2010 7:38 PM

Purchased for a 2005 GTO. Did not make a huge difference, but I can feel more power in the mid RPMs. Throttle seems more responsive and revs stronger than before.
