Riding sled when I lost all boost.Idles and starts good doggy and will only rev. to7000 RPM.Checked turbo fins,boost lines and exhaust for air leaks found nothing .Beginning to think its not the turbo but a sensor or something else also checked spark and compression they were good. Please Help find problem.

Throttle bodies blew out of the boots.

Checked intake boots at cylinder head and fuel rail plus checked boots from fuel rail to intercooler all were on and tight.
