hoping efi logics can set her straight on the re-tune day. previous owner gingertooth had it tuned by you and dave brown at mspt on a safe tune for the stock trans
Are you using NGK plugs? Its probably not running right as it was not tuned for that boost. If you use stock or one step colder copper or IR NGK plugs gapped at 026. You wont misfire at the boost I tuned it for. If I tuned it, Send me some logs with the map and I will see whats going on.

Maybe you can get some of those special Race coil packs from Vlad. I hear they are bright pink and make another 15 whp.

Oh and yes, My V7RA motor came with black coil packs. The original ones. Pretty standard stuff.
