What's your fuel pressure at WOT?

Did you tune it after the upgraded fuel injectors and larger engine? Idle and driving around it should show around 14.7 on the wideband. I wouldn't try the wot anymore until you get the tune sorted out.

Yes it was tune once bigger engine and all components were installed .will be checking fuel pressure as soon as I get a gauge but Iím starting to think it might be fuel related as it tends to die when I come to a complete stop sometimes also or any other ideas

Are you running Open Loop or Closed Loop? If you're Closed Loop do you have any Fuel Trim data? Do you know if you're getting Power Enrichment? Do you have more than a 1/4 tank of gas in the car?
