[QUOTE="decipha, post: 15914724, member: 74327"] you cant directly compare completely different setups e85 is completely different than pump gas yes i shoot 27 degrees or so to 4vs on e85 on lower boost levels < 15 lbs or so on higher boost 25+ i usually dont exceed 20-23 depending on amount of boost and how they want it correct, 20 deg is usually all a boosted 4v wants on pump 8 deg is at peak tq, nothing to do with timing up top, the 4v engines dont like alot of timing at peak tq, Ive taken them from 8 deg to 24 deg at peak tq and it not make much of a difference. The 4v engines also are not tolerant to high compression at all. The higher the static compression the less timing they want. I have a post on the efidynotuning forum with good info, search for mach1 [/QUOTE]
