During an engine break in period, how bad is the gas mileage before a tune ? For info sake, 4.6 sohc bored to a 4.8, new cams, exhaust and all the works. Would the car drive really badly ?
If untuned (meaning no base tune), could damage the engine before you get it broken in.

spine deck for the win. I just got my back to crack, felt like L4/5

Correct move IMO would be get your tuner to write you a base tune for startup, then drive it gingerly around block, datalog, send file and get revision. Do that 3-4 times until you have a decent base map to complete the break in miles then bring to dyno for full throttle tuning and drivability dial in. Or remove the blower, toss the stock injectors/maf and intake system back on and run it on the stock map until broken in then bolt the speed parts back on and trailer to a dyno.
Now, if the blower, pulley, fuel system, intake routing, and maf are all the same as before and your tune wasn't shit you likely can bump the idle to account for the new cams and watch your AFRs carefully during break in but I would still rather spend $500 on tuning a new base map vs blowing the freshly built expensive hard parts to bits.
Yes base tune should be matched to your combo of parts BEFORE so much as starting the new engine.
mosquitos are a trending topic recently. if you want to learn about gene drive mods there's a good Netflix short series on the topic. IMO worth a watch if you want to learn a little about CRISPR tech and genetic mods
