cool!
on a side note, plugging that hole has fixed it right up!! starts like it should and runs a hell of a lot better! still doesnt want to shift at WOT though... hmm... hope its just some sort of TQ management in the factory tune and not a trans issue!

Is the truck tuned? No torque management like you would think in a gasser, the laggy shifting at WOT is 99% because your getting air in the fuel system, usually at the filter sealing area itself.
Or, if it's tuned, you are running out of fuel in the higher RPM's due to no aftermarket lift pump.

Nope, not tuned... Truck is bone stock. It just won't shift, if I'm over about 75% throttle when it's time for it to shift it just hold whatever gear for 2-6 seconds I'd say then will eventually grab the next gear
