228r question I have a 2006 silverado 5.3 which is all stock except for exhaust and I just put a 228r 112 cam in it. No tune. It will idle but when taking off it seems real sluggish until like 3500-4000 Rpms it keeps throwing a p0300 random misfire And a p0101 maf code I put new plugs and wires in it and swapped all 8 coil packs from my other truck it didn't help it. Will tuning help?? Any advice will help thanks

That's a pretty good sized cam for a 5.3, so yes you're going to need to tune it.
I would suggest going to a professional tuner, doesn't seem like you really know what you're doing and HPT can take a while to learn and tune a cammed car. You're also going to have to invest some money in a wideband to go with the software, so might as well just have it done by someone that knows what they're doing.
