Ford Performance Stage 2 Power Pack Upgrade for all U.S. and Canadian 2015, 2016 and 2017 GT Mustangs.

We are proud to offer you the opportunity to pre-order the new Stage 2 Power Pack Upgrade (P/N: M-9603-M8A) for your U.S. or Canadian 2015-2017 Mustang GT from Ford Performance!

This Ford Performance Stage 2 Power Pack Upgrade Package will give your GT S550 up to 21 peak horsepower, 24 peak lb-ft of torque and up to 40 lb-ft of torque at only 1500rpm. You will notice a huge improvement in your Mustang's off-the-line responsiveness with improved and enhanced throttle response and a performance feel. Automatic transmission calibrations feature an optimized performance shift schedule while manual transmission calibrations feature an exclusive “No-Lift” shift strategy.

This will require a plug to be used with the unused port/fitting on your new cold air intake tube when installing on all 2017 GT Mustangs built after 9/16 only. The production date on the vehicle (month/year) is located on decal in driver side door jamb.

Rated 5 out of 5 by from Power pack 2.... worth the wait!! I preordered this in September and just got it a couple days ago. Installed today. It took me longer than it should have; about 4 hours. That was with the added trip to the hardware store for a 10mm deep socket. The hardest part of the install was removing the symposer tube. Getting to the bolt on the firewall is pretty difficult. The instructions were not great to say the least. LMR has an install video and it's good, but doesn't touch the quality and depth of BIll's install videos. Hopefully he'll do one soon. There's almost no instructions for the flashing of the ECU. Not difficult though. After the install, it sounds great! And looks awesome! It's a must buy if you want more power and want to stay legal.

Rated 4 out of 5 by from Worth every penny The install is easy. Throttle response is better, but not instant(a little disappointed). The power you can feel. The car just keeps pulling, way harder than stock. I have an auto and the shift schedule is smoother and better timed, not too harsh. The best feature is one I wasn't looking for. The sound. I have the MBRP street cat back on and always liked the way she sounded. But now, wow! The tone is much deeper and just a bit louder. The filter is paper and not reusable, but I'll replace it anyway. I love the package

Rated 5 out of 5 by from Great Bolt On Upgrade! Bought this Wednesday on the phone and picked it up from Anthony the same day. Then had it installed Thursday by a Ford dealer local to my work. Works as advertised and it is power you can actually feel. Low RPM range is where this shines in my humble opinion compared to the stock configuration. Also pulls very good through the upper RPM range. If you want to retain your factory warranty without any questions, this is a great upgrade for your S550. I am normally not a five star rating guy as products need to exceed my expectations. This pack does just that! I don't know if it is because I have a cat back exhaust or not, but I'd almost bet my life this added more power than advertised. Wish I would have had my car on the dyno before and after installation.

Rated 5 out of 5 by from Awesome value and performance! Purchased this kit a couple of weeks ago, CJ Pony Parts not only had the kit available when nobody else did, but it was shipped and at my door faster than expected! Had dealer install to keep warranty in tact and the performance gains from this are astounding. DEFINITELY worth the price and if you want to keep your warranty and have the added punch to your 5.0, I highly recommend giving this a try. Well worth it in every way!!

Rated 5 out of 5 by from More Responsive The car is more responsive, especially on the low end. The sound is much cleaner too without the sound symposer. The 10mm bolt on the firewall was a little difficult to reach. I used a ratcheting wrench with a flex head to get it off. Other than that it was a smooth install. Took about 3.5 hours. Instructions could be better but you'll find your way through it as you get to the various steps.

Rated 5 out of 5 by from More Power!!! Just had the power pack 2 installed at the dealer so that I would retain the factory warranty. Throttle response is amazing! Great price at CJPony!

Rated 5 out of 5 by from Wakes the car up 100% worth the purchase, this is how the car should of came from Ford. Throttle Repsose and the lower end power band has a very noticeable increase.

Rated 5 out of 5 by from Definitely worth the wait and effort Had to wait awhile to start upgrading my 2015 and researched all the intakes out there. Decided on PP2 because you get more for your investment. The larger TB and stock appearance raises above most. If your going to upgrade make an investment and get value now and later. The install went as expected, except I had to extend the MAF sensor wires by trimming back 3-4 inches of tape. NOTE: After programming and validating everything I got MIL on first drive away from house. Checked code using ProCal diag screen and shows P0315 cam sensor learning. You can clear this using ProCal "profile learning" switch on the configuration tab. Warm up engine then start learning option. Rev engine to 3-4k then release and repeat 5 times. The MIL cleared and then diag shows no DTC. Response is great and definitely feel low end torque and vacuum gage instantly jumps to near zero on punch. No idle issues or NVH except it does wake up my 3in cat-back tone.

Dave! Do you know if Ford honors a Certified Car Warranty if the kit installed by an authorized Ford dealer? My car has about 15K miles on it and is protected by the Certified Warranty for another 3-4 years or 100K miles. Thanks!

Asked by: 50thWW
If a ford dealer installs it they should honor the warranty but you will have to check with the dealer that would be doing the install.
