Today we had our customer Jason Peaslee bring his 2014 Roush Raptor to our shop from West Virginia. Jason brought the truck 5 hours to New Jersey this morning and it was at our doorstep first thing this morning. We went right to work removing the factory installed spark plugs. A set of 16 NGK Iridium 6510 spark plugs replaced the factory Motorcraft plugs. The NGK plugs are a 7 heat range which is colder than stock and provide better spark and less chance of detonation. The plugs were gapped to .030" to allow for longer change intervals and to limit spark blow out from Boost. After the plugs were changed we strapped the truck down on the dyno and made a test pull with the Factory Roush tune. The motor had plenty of time to cool as the plugs took nearly 3 hours to swap. With the Factory Roush tune the truck made 439 RWHP on 93 octane. We loaded our JDM Custom tune in and made a pull no more than 15 minutes after our test hit. With the engine warm and the intake temps hovering around 20-30 degrees above ambient to start the run and the truck made 515 RWHP! We backed it right up with a 2nd pull and the engine full temp it made 500 RWHP on the button! Total power net gain of 76 RWHP !!! All this from a custom tune!
Now we are able to improve the performance this much only tuning the truck because Roush does have a very mild tune up in the truck. They run a very rich fuel mixture and limit throttle angles at both part and wide open throttle. As well Roush incorporates a 100 mph speed limiter which creeps up on a 650 HP very quickly. So we have raised that to 130 MPH, to go any further we highly recommend a Axle Exchange Aluminum driveshaft for better balancing and safety. On top of this our tune also provides better Shifting, Throttle Response, and all around Driveability. The customer stated he got 11 mpg average, now he should see about 14 mpg average on his way home going on what we've heard from other customers! All of this from simply installing our custom tune!!
Dyno Graphs to come...
After fighting with my scanner for the past couple hours
I gave up and took a photo of the graph. I over laid the stock graph and the 2nd run of our custom tune, we started them at the same RPM and gear. The 515 HP run didn't look as nice over the stock run file. You get a better visual of what your gaining from our tune this way. As you can see from the hit of the throttle all the way to about 4,500 RPM we gain average 15-20 RWHP. As we climb higher in RPM the power gain increases. By 5,000 RPM (104.7 mph) where the Roush tune hits the speed limiter we are about 30 RWHP over the Roush tune. After the speed limiter is raised we can take the truck all the way to redline, 5500 RPM (113.5 mph) and peaks our total power output at 500 RWHP. A Total gain of 61 RWHP peak on a hot engine! What is also note-able the Torque gain also starts from the hit of the throttle and carries all the way to redline averaging about 30 lb/ft more than stock. A total of nearly 27 lb/ft of Torque peak gain!
