For starters, I love the Roush! It's one of the sickest new Stangs IMO. I hope you have the best of luck with it!
Thanks Shane! One of my personnal favorites as well!
I did have a PM asking for more info on the tune and my impressions of it. Since the reason we have a forum is to share info I figured I would post my response on here as well. Again this is all my opinion... using my butt dyno and my reading prior to purchase. By the way, I am now 1/2 way through the next 93 Race tune and I am running at an incredible 25.2MPG! Thats about 90% highway with the rest stop and go.
First of all, the tune is the best, cheapest way to get horsepower, plus in the case of the Coyote it makes the motor much more effecient as well (read better MPG) as well. I am curently running through my second tank on the Race tune and running 25.2MPG, impressive. Of course that is 90% highway running about 70mph.
Anyway, throttle response! The factory Ford setting does not give you full throttle immediatley, it brings it in slow, through just fractions of a second, but its enough to keep the back tires from spinning uncontrollably and also provides better MPG at highway speeds. With the tunes, the throttle comes in quicker. I was trully expecting it to be more neck snapping when it comes in, but its decent, even with the Race tune. It makes the car feel faster although probably does not do to much in 0-60 times, and definitely makes no difference in HP, torque figures. I woud compare it to a mild gear change as far as how it feels when you initially punch it. The biggest improvement on the tune to me is the mid-high HP. The Butt dyno is very impressed with the gains in Race tune, but not to noticable in the performance tune, but there is improvement. The 40-120mph times feel like they are a second faster, although I know they arent... it just feels that much faster. According to what I have read HP gains are about 30HP to the race tune. That feels about right but without putting it on the dyno before and after there is know way to know for sure, as every car is a bit different.
Warranty.... the biggest reason you are probably hesitant. The Bama tunes Warranty only covers you if Ford determines it is the tunes fault that you have an engine failure. And then only for a limited time (I think its till the end of the factory 36K mile) You have to remember there are thousands of these tunes out there and very little problems, to my knowledge Bama has not had a single engine failure from their tunes, although there have been a couple of issues that had to be resolved, idle problems etc. These things happen with any software!
I am VERY pleased so far with my tunes. After I run a few 93 race tune tanks through it I am going to swap out to 87 Performance and see what its like. I expect 10-15 HP loss (factory is 10HP from 91-87octane) but it is supposed to retain the throttle response and torque improvements of the 93 performance tune. I will post as soon as I get some butt dyno numbers.
Go for the tuner, you wont regret it!
