Hey guys, is there a device, Im thinking of MSD or something like that that would work in my LS engine, that can adjust the timing on my engine when I want to run NOS? and have Allen tune my truck the way its supposed to run without NOS? cause Ive been having detonations between every gear when Im racing in 4LO because it hits the rev limiter, and people from here tells me Timing can be an issue, cause my tune is tuned to run with nos and I wasnt running with it...
anyone?
