From day one, my TH has not felt much more powerful than my last SRT8 with the 6.4l. it now has 2500 miles on it and have been testing launch mode at all RPM ranges and the best time is 4.2 seconds. I'm running the Pirrelli stock 4 season tires at 30psi. Noticed today that with launch mode enabled it is showing zero boost psi, and after launch it showed a maximum of 5 psi. Any ideas what might be going on here?
