6.4L - 560/1110

[08stroker250]

Got on Dunbar's dyno yesterday at Smokin' 09. Put down 560 horsepower and 1110 foot lbs. This was with the "310" Spartan tune, DPF/DOC delete pipe, and AFE stage II intake. Only other mods I have are EGR delete plates and a Suncoast direct solenoid. Pretty good numbers I thought. It was 571/1133 with standard correction.

What version do you have?

Nice numbers !! that's a high horse tuner for numbers that close to mine. 450 are rated at less horses than 350/250 from the factory. Think spartan is fibbing on numbers? Are those your exact numbers or are they rounded? If rounded I am 540/1100

[08stroker250]

Those are exact. The first pull was 560/1110, second pull 559/1104, and the third was 558/1103. That was with the correction factor for temp, humidity, elevation, etc. The standard correction was 571/1133. David said that it was very smooth on the dyno and that he had absolutely no issues with it, he also stated how impressed he was with the consistency and smoothness of the power curves

And when you say fibbing, what are you referring to?

"310HP" TUNE I think mine is 200HP I just figured you would be closer to 600 with such a high tune have you ever done a baseline to see your real gains Still great numbers for no more done to the truck ask the Dodge guys that I bet out yesterday with $$$$$$ put in there trucks

No body at Spartan claimed the 310 numbers, that was a rumor that got started up. The orginal "310" tune that I have is labeled as Brute Power which is what Matt named it from the start, nothing about 310 horsepower. The rumor caught on though and now everyone refers to is as the 310 tune, including Matt. Some things just stick. The truck that Matt posted the dyno sheets for this past week ran the "310" test tune on a dynojet dyno. The truck dynoed stock on the same dyno at 280 rwhp. They loaded the "310" tune and the truck made 592 rwhp. That is a 312 horsepower gain from the stock numbers. I dont know what kind of correction that dyno used nor do I know what load percent was used. I believe the dyno I was on was loaded at 40%. I also think there is a glitch in my fuel system, or a glitch in the tune/calibration causing my rail pressure to spike and cause the truck to defuel. If its a fuel system problem, then that could be why my number is so low. Just going to take more testing to figure it out.

And I highly doubt that your truck will do 337 stock....I am guessing that your tune is probably more like a 250 or 275....

Unless your truck is a manual or and auto with a 4.88 rear axle then it is still the same as the 250 and 350. Just wanted to point that out to you. Not saying that your truck doesnt qualify, just stating the facts

That is what I ment "310" would be somewear around 600 like the 592 posted Just some miscommunication I am happy with mine and am not chasing any more numbers just wanting to know what I was putting out. I might run it on my tow setting to see what it is doing that is it Again great numbers keep us posted on any changes you do for power increases

cool cool.

Sounds like you need to make it to the track and just kinda prove things that way... Nice numbers anyway. I need to make it back to a dyno as well....
