Misfire on #8 at 5000rpm help

[vsellens]

There are a lot of things I dont like in the tune, but I suppose it should work fine if thats what so many people use.
I have yet to hear of it being a problem, especially with the car being stock, but I never liked how the fuel rails are fed on the eforce. #8 gets fuel last and could possibly get short changed on delivery. I have changed mine to feed directly to both rails. I suppose it is a possiblity especially if the pressure got a bit low.

I did the same with the fuel rails it didn't help.

Ok running richer doesnt help. I changed injectors and ran pig rich and the problem got worse.
