Just a complete guess but what about the ignition switch? :dunno:

and about the no cat on a stock truck .. yes at WOT you'll overboost and the computer will atempt to save your motor from shooting a pistion out the side by retarting the timing some.. and yes this would/could be cause by your exhaust flowing too much and the stock wastegate not being able to keep up with it.

Re: no start

You need a cat. I tried taking off my cat and the boost was bad and the truck ran bad. Is it crancking but just won't start?

yes its cranking but not startin youll get a cough out of it and then after that just strictly cranking
