Deliceous uses a weird hybrid SPEED Density type tuning on many turbos which relys on MAP (pressure sensor) for fueling not MAF.

Check fuel pressure and fuel pump

and for intake or exhaust leaks

check all hoses including ones under intake manifold clamped

They are the common causes
Battery volts check good.

Will recheck DI computer, it was taken loose during install.

If nothing else is found may just replace MAP sensor.

Have the + flex fuel, should get limp mode if fuel pressure is low.

Do not hear any exhaust leaks will double check.

Manifold pressure is good at idle do not suspect any intake leaks.

Thanks for the info!!!!
