The more submissions we get, the more info will be publicly available.

I really dont understand much of whats happening in this thread so can someone baby me thru this?
I paid justing whitted (twisted tuning) $425 like 3 months ago for email tune. Im running mhd with jb4 backend flash. As of recently im getting a misfire. I step on the pedal and suddenly an incredibly loud pop occurs and i lose power. I read codes and it says cyl 5 and cyl 2 are misfiring. I changed my plugs before tuning and ive been going back and forth with him increasing boost and such. I dont run meth, and i dont get any of this. I use shell 93 if that means anything and im scared that ive been scammed. Can i forward the whole email list to someone knowledgeable and see if maybe you guys could help? I can provide a misfire log or anything else, please just someone help?
