Clutch? FICM? No Idea, Need Help

[Paul04_619]

Hi I have an 06 F350 six speed SRW SC with a new oil cooler, egr delete, and an SCT Livewire, Xtreme street, and when i get on the throttle halfway or more it surges about 500-800 rpms around the 1800-2000 range and then goes back down to wherever it was and continues to pull normally. Is this the tune, clutch, ficm? or something completely different?

I doubt it's FICM related. It just doesn't sound like something the FICM would cause. Without actually being in the vehicle it's tough to determine what your "surge" really is, but it could be the engine overpowering and slipping the clutch or could even be wheelspin. It's tough to say. If RPMs are changing without a corresponding change in vehicle speed, it's most likely the clutch. Outside of that, we'll need a little more info.

Take care.

Sounds like a slipping clutch. I'm not sure but there might be a way to shine a flash light up there and see if you still have friction material left. Could have a pressure plate going weak as well. Look for signs of a bad read main seal that is lubing your clutch and causing slipage.
