Hi there, car running stage 2, new spark plugs, new coil packs, redid rocker gasket but logs (attached) are showing loads of misfires, most on cylinder 3, sometimes 2 cylinders at same time. Logs are from about 20 minutes of driving with a 3rd gear 100%pull, which also shows a misfire, typically in lower rpm.

Spent so much on this car just at a lose what to do. Weird thing is, don't feel any loss of power when driving, so wondering whether most of these signals false positives (e.g. I wouldn't think there was a misfire had I not logged it)?   

Thanks in advanced
