Installed a 16g turbo kit along with software and fpr and new plugs in late spring, after about 500 miles i have developed a miss on cyl. 5 & 6 could this be because of the spark plugs. The plugs installed are ngk laser platinum #bkr6equp part #3199 it is softronic software from vivid. Was advised by vivid to install denso ik22 plugs any other input.
