I don't think a tooth off would cause this. Why?

I advance my cam 1 tooth when towing heavy loads to lower the powerband... I get amazing torque off idle, right up to about 3,000 rpm. It falls on it's face after 3400 rpm, though.

If I retard the timing a tooth, I get no power off idle, but high rpm torque. I see no practical purpose for this setup, though, so I don't use it.

When spot on, I get decent torque from 2000-4000 rpm, and decent overall performance (EB 270/430 cam). It's a bit high on the powerband, but it suits me perfectly trying to run down the autobahn at 100+ mph.



I would be leaning more towards a torn intake boot. When he hits the gas, the tear opens, allowing enough unmetered air into the system to stall the truck.
