I dyno'd my truck today at Beans with the 275 spartan tune. I only pull 433.7 hp and I think it was just over 900 ft lb's of torque. I figured its would do better considering the 530+ put down down by the 310 tune. I loose some by the 36's I know.
for what its worth he is a vid of one of my pulls seams like the smoke clears up pretty good on my run, course i comes back when the turbo's get out of the effieciency range. last run video by dzchey21 - Photobucket
beans dyno has been over 100 low before..i remember at the spring dyno day everyone was WAY lower than normal, even bean's truck. dont worry about it, just go to the track.
Yea, that's not right. I dynoed 549 uncorrected with the 310 tune. Most guys are pitting down 510-530 with the 275 when loaded right before the dyno is done. Like Mike said, hit the track and your trap speed should show you more than the dyno.
You didn't reload the tune before you dynoed??? If you don't reload right before the dyno, you won't get full potential numbers. The ECM on these trucks learns fast and begins to "kill off" the power
Yes, I am serious. There are many threads brought up about this on the Spartan forum. The ECM has adaptive learning on these trucks, and overtime it kills the power.
I don't think so, i've had my looney tune from DJ in for along time and i've dynoed twice and had the same numbers each time... Never heard of that, of course mine is a 6.0 so i dunno if that makes a difference....
With the fact that you run the 310 tune, you might have one of the files that Matt has fixed the adaptive learning with. He is trying to play with it some, and he thinks he may have a fix for it. It is part of the testing with the 310

There is adaptive learning for sure, i think matt is learning how to get around it but im not sure, the thing is about the track is you are pounding on it consistantly so the trans, and engine are expecting it, i tell you want both times i have got on the highway after drag racing and it pulled harder then it ever has so i think it adapts the other way too.
after i got a custom street file it is still getting quicker and smoother everytime i drive it and i have put 200 miles on it, but they say it "should" learn in about 30 ?
I pound on it everday. I can't help it. I can't get this truck to even chirp second. My 06 on 38's on stock gears did that. I gotta a feeling somethings wrong. I emailed them last week, now just waiting on a fix or something.
Have you attempted to reload the tune yet?? Might should give that a try and see what happens. My truck will be all over the road in the 275 if I floor it from a dead stop in 2 wheels drive
Nothing different. Just waiting for something back from the email I sent to Spartan about it. Pushing a week now.
