It starts ok..It runs good at idel..But when I put my foot in it it bucks back and forth like a raging bull...Acks like it is hitting overboost...

All this bucking only happens when I'm driving the car..It revs. ok when I'm at a stop..Put your foot in it a little it starts to loose power..Put your foot in it all the way it loose power and then it starts to buck and the boost starts to fall off..

The car will not die it will do this all the way down the road with out dieing..

I have no clue where to start..I'v check timimg at lease 4 times and I know that its died on the money..Would love to get this thing to pass its self up one day..
