Just do yourself a big favor and go get the car dyno tuned. A tuner guy can nail the cars problem and line it out to where itll run good.

Keep in mind that you upped the displacement from 3.8l and the computer can not compensate for the extra cubes .

Makes total sense is there anything I can change for upper plenum or another computer that you would recommend

Anytime you change an engine parameter, such as timing, displacement, valve events like camshaft,....the stock computer is lost. Dyno tuning is the best solution. Getting a dyno tune isnt cheap either. Be sure your desired engine modifications are complete to maximize the cost benefit of dyno tuning.
