When I upgraded to Patch U my throttle would cut out every now and again usually under WOT. It only be a second or so blip. I re installed Patch T and no probs.

Nobody? I suppose ill have to reinstall patch U and save a replay

I lied
its doing it in patch T as well... still need to save replay... could this be controller related?

Yes, it's very likely a controller issue. Probably the pots on your pedals need some cleaning, but a simple recalibration of your pedals might fix it for some time, too.
