6.0 run away

ok as it states ive been experiencing some some odd issues.... my 05 has a SCT tuner with IDP tow tune and agg, street tune, in tow tune it runs great but in agg, street say on a free rev you rev it up to about 2800 rpms and the sucker screams to a little over 4000RPMS without being in the pedal same as for driving awesome low end power nice and smooth then all of a sudden the trucks takes off like a bat out of hell and will rev way past 4k as in the truck keeps accelerating extremly fast up to 90MPH with maybe 10% throttle pretty scary but on the tow tune its like driving a normal truck just perfect. well i have my custom tunes set for the powermax turbo that im getting at the end of the week but i dont think that could make it do that unless i had sticking turbo vanes maybe over speeding the engine but i dont see over 28psi??? any help would be greatly appreciated. i sent an email to IDP waiting to hear back from them

Had one do this same thing. It was after we installed a set od Dynomite Diesel stock injectors. Dynomite wont warranty them unless the oil and fuel cleaner they give you with the injectors is used. I followed the directions and put the oil cleaner in the oil and road tested. Exact same situation. Truck would take off and had to hold the brake pedal with both feet at one point. I noticed while this would happen the ICP and IPR were all over the place. Its like the IPR could not do its job. Try monitoring the ICP and IPR and see what it is doing when the issue is occuring.

just waiting for a reply from erik at innovative. my new turbo will be here friday and when i put it on ill retune it and do a free rev and see if it does it and if it does ima have to have the tune worked with. i hooked up my laptop with fords software from a buddy that works there and every single thing sensors pressures are all in the green so something in the tune that doesnt like me truck i guess which sucks cause it was so awesome but i knew something was wrong so i cant run that file for now till i figure out why its doing it. when i mean rocket i mean 35'' mud tires lit up at 45mph and billowing white smoke behind me lol

Does it seem like the trans is slipping maybe thus causing the rpms to spike? Truck wouldn't be accelerating normally though. My Xtreme Street definitely can be like a switch as far as the power sometimes. Not as dramatic as you are talking about but there is a sweet spot in the pedal where it just wants to get up and run!

I've wondered about these tunes tricking ICP into reading much less than it actually is. You're trying to reach a desired ICP at WOT the PCM is thinking it's much less than it actually is. When you close that IPR off the engine will rev up on it's own.

yeah it doesn't rev up slow like a free rev you can hit the throttle and say it would go just past 2800rpm and it just speratically revs to 4000+ rpms
