There is a tuner trick when setting up the Split Second for a six cylinder.
Mark at Split Second told us when setting up the R4 file to set at 3 cylinder-2 stroke instead of 6 cylinder-4 stroke.
This gives a better firing pulse.

You're running a four banger?

Give Mark a call at 1-949-863-1359 you should be able to maintain a 12.5:1 under boost.
