Misfires close to Redline on full load
Hey guys,
I have got an e85 remap for my 05 Convertible Z, and since then I have some small misfires happening when i'm close to the redline (like around 6400-6700rpm). It's like the fuel stopped coming for a tenth of a second then comes back to normal.
The mapper told me that it may be my ignition system that is old and that I should start by replacing it. I have then installed NGK Iridium Spark plugs and Reinforced coils from HP-Ignition. It changed litterally nothing. Still the same misfires..
Before i remove my injectors to get them verified by a shop, does anyone have an idea of where the issue could come from ?
Thanks !

Do you have an AFR meter? A very rich condition may feel like misfiring. If your injectors are fine at every other rpm it would be hard to believe they are just not working above 6400
