i have been reading and reading and im more confused than when i started. i hope you guys can make some things a little clearer. is the diablo tuner able to tune blown hemis on our trucks yet or not ? does the diablo have an option to delete the signal from rear O2 sensors ? and what has to be done to the fuel system to run only 4 or 5 psi of boost ? another thing is i keep reading you cant go WOT past 2nd gear and no hard downshifts ???? how do you guys drive and race them without doing that ?
