[QUOTE="Mach828, post: 15015308, member: 102965"] His chart is 27* at 0 boost and is a blanket 4.6 4v amount. I've taken my e85 4v up to 27 degrees on e85 NA and it hit MBT at 23 degrees verified by the dyno output. I continued to add timing and it made no change in power. It doesn't matter what you change the top of the spark table to be. If you leave it at 120% it doesn't matter if it reaches 200% actual load, its still going to use the top row. Go run 27 degrees and have fun rebuilding your engine. Once again, go look at the trend from the stock MBT table, compare it to the SCT value files, and develop your own table. You don't have a dyno and you don't have knock sensors, so don't get too greedy. [/QUOTE]
