i am running a built LS/VTEC turbo... i need to find a good way of retarding the timing besides turning back the distributer. i have a greddy e-manage and profec e-01 but yet have installed it. does the e-manage retard the timing for you according to boost or MAP? i was thinking of going with a MSD 6BTM but i heard that people have alot of problems with it so im not so sure bout it nemore. anyone have any experience?? please let me know.. thanks JuN
