No codes in any modules. 4WD version. In a 10 mile drive it will do it maybe 3 times. Always above or around 60 MPH. Acts like someone hit the brakes for about 1/2 second or less. Determinator scanner data... yes a little laggy but only selected a few items to speed up things. No voltage drop or spike at APP sensors. All Wheel speed sensors stable. RPM data stable. No change in ASD relay status. Didn't see a change in injector #8 pulse width data either. I dont know witch 4WD system it has...has small chrome paddle for 4WD low and Neutral below shifter. No change with traction control on or off. Way harsher decel than if I lifted off throttle. I don't want this thing eating my lunch... Suggestions to determine the system responsible. Noticed have brake pressure data available, don't know if this is interpolated or actual...definately not high pressure (found that PID too late in the day)
Thanks
