MAP for E85
Just switch over to E85 and running 4X1680's, running very rough and spitting out fuel. Anybody has a MAP setting to get me in the right direction? No datalog, just the handheld for now.

The 1680 primary injectors are your problem. E85 will take about 34% more injector capacity to produce the same power as E10 gas which is very common now.
550 X 1.43 = 737 for stock primaries. Now 850 primaries are more difficult to tune than 550 with gas but would work well with E85. 1680 primaries with E85 is equivalent to running 1253 with E10 gas. Way too large.
Running 850/1680 with E85 would be like running 634/1253 with E10 gas which is too small to produce over 400 hp.
Run 850/850/1680 or 850/1680/1680 with an Xcessive manifold.
