FBO now misfire time for a tune up!!!

Ran cobb stage 1 +fmic for a month then went to FBO and ran for 2 weeks on cobb ots stage 2 +fmic. Car slowly started shaking a little at idle and then after a few wot the SES light came on. Cobb reads misfire cylinder 1. Got ngk plugs and delphi coils on order will be doing a walnut blast when installing them both. Hope this will fix the misfire. Car have 72k dont think its ever got coils replaced and a walnut blast done. Car was running super strong and idles perfect before modding it. Planning to get a protune instead of just ots cobb maps after this.

Yep, you're right. It's plugs or coils or both for that misfire, and yes, a tune is WELL worth the money.
