Charley N., 2005 GTO

Reviewed By Charles N (El Dorado Hills, CA) Reviewed for a 2005 Pontiac GTO —10/2/2015 8:48 AM

I found the installation very easy. It doesn't hurt to read the directions first. I installed only the standard Performance upgrade first and it did create a noticeably better acceleration. My GTO is an automatic (4-speed) and it definitely shifts smoother under full throttle. It also shifts smoother under normal driving conditions. I'm hesitant to bump up the shifting pressure in the more detailed performance upgrade system; it's still a 10-year-old transmission, albeit a strong one.

05 GTO, not sure if its worth it

Reviewed By michael c (fort pierce, FL) Reviewed for a 2005 Pontiac GTO —4/17/2012 7:09 AM

I'm getting about 3- 4 mpg better, performance is difficult to rate. It needs more tuning options for the novice who is not familiar with the settings. There is not enough info with the product that tells you what different features do. Install is easy, as long as you have some computer skills, basic skills. Big price tag, not sure if its worth the bux.

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.
