As many of you may know we got our 2013 Mustang GT last Saturday and starting modifying it right away. We added Suspension, lots of dress up stuff and a set of Flowmaster mufflers, but now it's time for some horsepower.
SCT released the '13 software Tuesday morning and we jump at the chance to see what this thing would do with a tune only and our JLT Intake and tune package.
We ran the car on the dyno last week in bone stock trim, right down to the 87 fuel and it made 360 RWHP and 336 RWTQ. Right on par with our '11, but smoother through the mid range.
So to get an accurate test today we base lined the car to see what the 93 fuel would do and the results were great. Nearly 10 more RWHP and 3 more TQ putting us at 369.83 RWHP and 339 RWTQ. Considering the only changes were 93 fuel, mufflers and our 20" wheels. We know that mufflers are more for sound than power and the heavy wheels could actually hurt power, I'd say most of the gain was due to the fuel change.
Next up we had Brent Hughes of Dyno Tuned Performance build one of his custom tunes for use with the stock air box. It's a big debate on what makes the power in a CAI & Tuner package, so let's test it again right here.
A few runs later and using the best tuned run, power jumped to 383 RWHP and 356 RWTQ for a gain of 14 peak HP and 17 peak TQ, but even higher gains of 15-16 HP and 17-19 TQ were seen through the mid range, very impressive, but not the 25-30 we typically see in our Intake and tuner packages.
So, now it's time to ditch the stock air box in favor of our custom painted JLT CAI in Gotta Have It Green.
Brent took his custom tune he made for the stock box and inserted our custom value file for the JLT intake. No timing, fuel or any power adjustments were made, same tune, just modified to run correctly with the JLT CAI.
We did 2 back to back runs making 393 & 394 RWHP and 364 & 366 RWTQ. We looked at the data logs and noticed we were down 1-2 degrees of timing verses the stock box runs and tune. When adding an intake your load tables will change and that's what happened, so we made a tune adjustment and hit it again.
Bam, 398 RWHP and 370 RWTQ, a total gain of 29 RWHP and 31 RWTQ from the base line and a solid 15-16 RWHP and 14-15 RWTQ over and above the same tune with the same timing and the stock box.
That's a pretty good gain no matter how you look at it, were happy with that, BUT being sooo close to the 400 mark we let the car cool down to try and make a glory run.
First run 401 RWHP and 372 RWTQ then we backed it up with a 400 RWHP and 371 RWTQ for a total gain of 32 RWHP and 33 RWTQ on a car starting with 93 fuel.
I mention the 93 fuel because some companies will base line on 87 and do their final test on 93 showing ridiculous gains, but they are unrealistic.
The car feel great on the street too, breaking the tires loose in 3rd on the way home.
So there you have it, the same gains we have been seeing for years on the '11 and '12 can still be had on the '13 with even better mid range pick up.
Next we plan on adding headers and catted X pipe followed up by the Roush Blower from our 2011 GT.
Here's the full video, be sure to watch till the end:
