1st time above 5000 feet. At 6000 feet, turbo boost would jump from 3-4 lbs to 25 lbs with just a touch of throttle. More like a switch. After several episodes my tow/haul light started to flash and my tranny wouldn't shift into 5th anymore. This is with DJs SCT street tune on my 04 F250. Anyone seen anything like this?
Thanks.
