Traction was bad before the procal and worse with it. It may be different at the track after a good burnout. You might be able to hook up but I would suggest a set of drag radials to slap on at the track.

 

We have the same Brembo track pack with the 3.73. On the rear I replaced the tires for wider 275/40 R 19 Michelin Pilot Super Sport on the stock wheels. Because of the tires that are bigger and/ or the tire itself "Michelin". The rear are almost glued to the road. They are much better than the Pirellis. You should try them.

 

After the Michelin I almost don't need to use the TC

 

Big improvement in "low end and medium range" performance with FRPP tune. Significantly more torque. Throttle response is very smooth, but pulls hard. Not at all "jumpy" like some aftermarket tunes. The shift schedule, with the automatic, definitely seems improved. Easier to get a downshift with almost no delay. Seems to hold in gears longer on the way up, even without WOT. Well worth the cost. The $100 for "dealer install" is cheap for the 3YR/36000 mile FRPP engine/drivetrain warranty. Not bothered by the 146 mph"speed-limiter".... according to Car & Driver. An aftermarket tune would fix that if I had a 155 mph mission

 

Sounds like I'm switching tires after I burn up the pirellis. Thanks

 

Thanks much. Yeah my Dodge was raised to 166mph top speed automatically with the first performance tune from Diablosport but I never even hit 140, I could have but I always seemed to run out of road first. Never was totally satisfied with the torque on that engine but I wasn't crazy about the idea of installing LT headers, under drive pulleys or catless midpipes either. All of that would have taken a trip to the next state to have th car dyno tuned and possibly wreck the cars streetability. And still not match the numbers a stock 5.0 Mustang puts out!

Ok, that's it, Im not mentioning the Challenger hence forth on this forum! Was just using it as a my only comparative reference as far as tuning and tuners go.

 

first gear, "useless"? Hmmmm.....

I have a 3.73, loaded GT '12 and I can hit 60 mph in a tiny tick over 4 seconds, on the road, with this tune and the Brembo Pirellis. Hook up is surprisingly good, considering previous Mustang GTs.

Pirellis PZeros regularly rate (in real testing) in the top 3 tires in the world for performance so, they aren't that bad. They don't last too long, they are stupid expensive and like most summer only, when the temp drops below 50, they start to go away for straight line grip. The Michelins will likely offer better dry grip than the P Zeros. the wet grip of the P Zeros, despite the high tread to void ratio and no siping, is actually amazing. We get ALOT of rain where I live.

the P Zero Nero all-season, OTOH, is pretty much crap.

 

I only have 3k on the car and I know I have some learning to do in launching this ride but I've had no luck hooking up with the pirellis. They handle great but for launching, not so much. I know tire brand can make a big difference cause my friends 435hp twin turbo M3 sticks like glue on cold tires. If you can get the pirellis to hook on a hard launch, please tell me how cause believe me, I've tried many times with no luck.

 

I've had the FR Power Upgrade Pack for a couple of years now and love it. Without being extreme, the settings are very conservative in terms of power and torque delivery. My car is totally different and it really becomes alive. Fuel economy is slighly better at 17mpg average, torque gains at lower rpms are very noticeable and that horrible skip ship is gone. Great product by Ford Racing, plus warranty is intact. i would definetely recommend it to anyone. I liked this product so much and its reliability that I just got the Ford Racing handling pack and will conclude rear end install this weekend ( completed Front end last Sunday). Can't wait to get to it.

 

The stock P Zeros pretty nice tires but wore real fast, switched to Contis Extreme Contact DW also very nice tires but softer on the sidewalls however considerable cheaper that Pirellis and lasted a bit longer. I just got Boss 302s wheels with 9 front and 10 rear rims with a set of Bridgestone Potenza Pole Position tires 255/40 front and 285/35 rear, grip is phenomenal, much better that with Contis or Pirellis. But only 200 miles on them still need to test them hard in autocross.
