I started having issues with my '99 T444E boost running smoothly. It doesn't run smooth and constant while driving. The boost doesn't engage immediately. After running and shut down I have difficulty restarting but not the next day. I have purchased a ScanGaugeD. I have a .1 boost which will go up to 7.0 once wide open.
Please help.
